Magneto-optic effects refer to phenomena that occur when the properties of a material are influenced by the presence of a magnetic field, particularly in relation to the interaction of that material with light. These effects arise due to the coupling between the magnetic moment of the material and the electromagnetic field of light.
The Cotton-Mouton effect is an optical phenomenon observed in certain materials that exhibit optical activity, particularly in chiral substances. It refers to the change in the polarization of light when it passes through a magnetic field in the presence of a birefringent medium, which is a material that has different refractive indices for light polarized in different directions. When linearly polarized light passes through a chiral medium and an external magnetic field is applied, the plane of polarization of the light rotates.
The Faraday effect, also known as Faraday rotation, is a magneto-optical phenomenon that occurs when the plane of polarization of light is rotated when it passes through a material that is under the influence of a magnetic field. This effect is named after the British scientist Michael Faraday, who discovered it in 1845.
A Faraday rotator is an optical device that utilizes the Faraday effect to rotate the polarization plane of light passing through it. The Faraday effect is a magneto-optical phenomenon observed in certain materials, where the application of a magnetic field alters the polarization state of light.
The Inverse Faraday Effect (IFE) is a phenomenon in electromagnetism and optics, particularly in materials with magnetic properties. It refers to the generation of a magnetic field in response to electromagnetic radiation, such as a laser beam. This effect is essentially the reverse of the traditional Faraday Effect, where an applied magnetic field causes rotation of the polarization plane of light passing through a material.
Magnetization reversal by circularly polarized light refers to the process of changing the magnetization direction of a material by exposing it to circularly polarized light, which consists of electromagnetic waves that have a specific helicity or rotational direction. This technique is particularly significant in the field of spintronics and magnetic data storage, as it offers a potentially fast and energy-efficient means to manipulate magnetic states.
The Magneto-Optic Kerr Effect (MOKE) is a phenomenon that describes the interaction between light and magnetized materials. It occurs when polarized light reflects off or transmits through a magnetized surface, leading to a change in the polarization state of the light. This effect is typically observed in ferromagnetic materials and is named after the physicist Johannes Peter Gregor Mendel (Kerr).
The photomagnetic effect refers to the phenomenon where the magnetic properties of a material change when it is exposed to light. This effect is often observed in certain types of materials, particularly those that exhibit a combination of magnetic and optical properties, such as magnetic semiconductors or materials with specific electronic configurations. When a material experiences illumination, the absorption of photons can lead to changes in the electronic states of the material, which in turn can influence its magnetic ordering.
Photomagnetism is a phenomenon in which the magnetic properties of a material change in response to light exposure, typically ultraviolet (UV) or visible light. This effect can involve the excitation of electrons within the material, leading to alterations in its magnetic behavior, such as changes in magnetization or the induction of magnetism in non-magnetic materials.
The QMR effect refers to the "Quantum Mechanical Remanence" effect, which is a phenomenon observed in certain materials at the quantum level, particularly in the context of magnetic properties. It describes how certain magnetic materials can exhibit remanence (the ability to retain magnetization) due to quantum mechanical effects, rather than purely classical magnetic behavior.
The Verdet constant is a measure of the strength of the optical rotation of a material in response to an applied magnetic field. Specifically, it quantifies the angle of rotation of the polarization plane of light as it passes through a material in the presence of a magnetic field. This phenomenon is known as the Faraday effect, which is observed in certain materials, especially in glasses and crystals that possess a non-reciprocal optical response due to their magneto-optical properties.
The Voigt effect is a phenomenon observed in the field of magneto-optics and materials science. It refers to the change in the absorption and refractive index of a material in the presence of a magnetic field. Specifically, the Voigt effect describes the alteration of the polarization state of light as it passes through a magnetized material.
