Magnetic Phase Transitions

Magnetic phase transitions occur when a material changes its magnetic properties due to changes in temperature, pressure, or external magnetic fields. For instance, as a material cools, its atoms may align their magnetic moments, leading to a transition from a non-magnetic to a magnetic state, like iron becoming magnetized. Conversely, heating can disrupt this alignment, causing the material to lose its magnetism. These transitions help explain phenomena like the behavior of magnets at different temperatures and are essential in understanding magnetic materials used in technology, such as hard drives and magnetic sensors.
