Spontaneous Magnetism / Magnetization

Spontaneous magnetization is the appearance of an ordered spin state (magnetization) at zero applied magnetic field in a ferromagnetic or ferrimagnetic material below acritical point called the Curie temperature or TC. Heated to temperatures above TC, ferromagnetic materials become paramagnetic and their magnetic behavior is dominated by spin waves or magnons, which are bosoncollective excitations… Read More »
