Half-metal 1970-01-01
Half-metal is a term used in condensed matter physics and materials science to describe a class of materials that exhibit both metallic and insulating properties depending on the direction of electron spin. In simple terms, half-metals are materials that behave as conductors for one spin orientation (usually called "spin-up") while acting as insulators for the opposite spin orientation (usually called "spin-down").
Magnetic semiconductor 1970-01-01
A **magnetic semiconductor** is a class of materials that exhibits both semiconductor properties and magnetic order. These materials can carry electric current like conventional semiconductors (such as silicon) and can also exhibit ferromagnetism or antiferromagnetism at certain temperatures, making them useful in a variety of applications that take advantage of both their electronic and magnetic characteristics.
Spin Hall effect 1970-01-01
The Spin Hall Effect (SHE) is a physical phenomenon observed in certain materials, particularly in solid-state systems, where a transverse spin current is generated in response to an applied electric field. Unlike the conventional Hall effect, which produces a charge current that flows parallel to the applied electric field and results in a transverse voltage due to charge carriers deflecting, the Spin Hall Effect is concerned with the generation of spin polarization rather than charge separation.
Spin Hall magnetoresistance 1970-01-01
Spin Hall magnetoresistance (SMR) is a phenomenon observed in certain magnetic materials and hybrid structures that involve a combination of magnetic and non-magnetic materials. It arises from the interplay between spin currents and charge currents in systems that exhibit the Spin Hall effect and magnetization.

Neft's work often focuses on providing detailed and accurate accounts of sports events, statistics, and athlete biographies.
Harvey Pollack 1970-01-01
Harvey Pollack was a notable figure in the world of sports, particularly known for his contributions to basketball statistics and analytics. He served as the official statistician for the Philadelphia 76ers, an NBA team, for many years, and was widely recognized for his innovative approaches to the collection and analysis of sports data. Pollack's work helped to shape how statistics are used in basketball and contributed to the broader understanding of the game.
J. E. Jayasuriya 1970-01-01
Rajan Hoole 1970-01-01
Rajan Hoole is a Sri Lankan academic and author known for his work on the country's civil conflict and issues related to human rights. He is associated with the International Association of Genocide Scholars and has written extensively on the Tamils' plight, the Sri Lankan government's actions during the civil war, and human rights violations. Hoole's research often aims to document the experiences of marginalized communities in Sri Lanka and to promote understanding of the complex sociopolitical dynamics of the region.
Plasma stability 1970-01-01
Plasma stability refers to the ability of a plasma—an ionized gas consisting of free electrons and ions—to maintain its structure and properties over time in the presence of various physical processes. Plasmas are typically found in stars, including the sun, as well as in laboratory settings and various technological applications. Stability in plasma is crucial for many applications, including: 1. **Nuclear Fusion**: In fusion research, creating stable plasma is essential for sustaining the conditions required for fusion reactions.
Resistive ballooning mode 1970-01-01
Resistive ballooning mode refers to a type of instability that can occur in magnetically confined plasma, particularly within fusion reactors like tokamaks. It is closely associated with the behavior of plasma in the presence of magnetic fields and the dynamics of pressure and magnetic pressure equilibrium. ### Key Concepts: 1. **Magnetically Confined Plasma**: In devices like tokamaks, plasma is confined using magnetic fields to maintain the conditions necessary for nuclear fusion.
S. Srisatkunarajah 1970-01-01
S. Srisatkunarajah is not a widely recognized public figure or term, and there are no specific details available on this name in common databases or references. It could refer to a private individual, perhaps in a specific professional or local context not covered in broader sources. If you have more context or information regarding who or what S.
Valentine Joseph 1970-01-01
Vicumpriya Perera 1970-01-01
As of my last knowledge update in October 2023, there was no widely recognized individual, organization, or concept known as "Vicumpriya Perera." It is possible that it could refer to a private individual or a lesser-known subject. If there has been any notable development or person by that name since then, I would not have that information.
Tanaga 1970-01-01
A **Tanaga** is a traditional Filipino poem that consists of four lines, each with seven syllables. It often features a rhyme scheme, typically of AAAA, AABB, or ABAB. Tanagas usually express themes of love, nature, or moral lessons and can be both humorous and serious in tone. The Tanaga form is significant in Filipino culture and literature, showcasing both linguistic skills and artistic expression.
Terza rima 1970-01-01
Terza rima is a rhyme scheme that consists of tercets, or three-line stanzas, which are interconnected through a specific pattern of rhyme. The rhyme scheme is typically ABA BCB CDC, and so on. In this layout, the second line of each tercet rhymes with the first and third lines of the following tercet, creating a woven effect that links the stanzas together.
Tornada (Occitan literary term) 1970-01-01
In Occitan literature, a "tornada" refers to a specific poetic form that is characterized by a structured, often repetitive pattern. It typically consists of a series of stanzas that include a refrain or recurring line, similar to what is found in other lyric poetry traditions. The term is most often associated with the medieval troubadour tradition, where poets (troubadours) would compose songs with intricate rhyme schemes and melodies.
Triolet 1970-01-01
A triolet is a poetic form consisting of eight lines with a specific rhyme scheme (ABABAHAA) and a particular structure. The first, fourth, and seventh lines are identical, and the second and eighth lines are also a repetition. This creates a musical quality and emphasizes the refrains. The form originated in the Middle Ages and is often used to express themes of love or nature. Its repeated lines can evoke a sense of longing or urgency in the poem.
Trova (poetry) 1970-01-01
Trova is a form of poetry that is characterized by its lyrical and often melodic nature. It has roots in various cultures, particularly in the Spanish-speaking world. The term "trova" itself can refer to a style of poetic composition that often involves the use of emotional and romantic themes, and it is typically performed in a musical context. In many cases, trovadores, or troubadours, were poets who composed and performed their works, often accompanied by music.
Verse (poetry) 1970-01-01
Verse is a form of writing that is often characterized by its use of meter, rhythm, and sometimes rhyme. It is typically associated with poetry, which is a literary art form that uses elevated language, imagery, and sound devices to express emotions, ideas, or narratives in a condensed and imaginative manner. Key characteristics of verse include: 1. **Meter**: This refers to the rhythmic structure of the poem, often marked by a regular pattern of stressed and unstressed syllables.
Villanelle 1970-01-01
A villanelle is a specific form of poetry that consists of 19 lines, organized into five tercets (three-line stanzas) followed by a quatrain (four-line stanza). The structure is characterized by its strict rhyme scheme and repetition of certain lines. The rhyme scheme is typically ABA for the tercets and ABAA for the quatrain.
