magnetic phase transition

A magnetic phase transition refers to a change in the magnetic properties of a material as conditions like temperature or pressure change. For example, when a metal is cooled below a certain temperature, its tiny magnetic regions, or domains, may align in a certain way, causing the material to become magnetically ordered (like a magnet). Conversely, if the temperature rises, these domains may lose their alignment and the material can become non-magnetic. This transition is crucial in understanding how materials behave in various applications, such as in electronics and magnetic storage devices.
