The Curie temperature, often denoted as \( T_C \), is the temperature at which certain materials, particularly ferromagnetic and ferrimagnetic substances, undergo a phase transition from a magnetically ordered state to a disordered state. Below the Curie temperature, these materials exhibit spontaneous magnetization, meaning they have a net magnetic moment due to the alignment of their magnetic domains.
