The Morin transition (also known as a spin-flop transition) is a magnetic phase transition in α-Fe2O3 hematite where the antiferromagnetic ordering is reorganized from being aligned perpendicular to the c-axis to be aligned parallel to the c-axis below TM.
TM = 260K for Fe3+ in α-Fe2O3.
A change in magnetic properties takes place at the Morin transition temperature.
Famous quotes containing the word transition:
“Power ceases in the instant of repose; it resides in the moment of transition from a past to a new state, in the shooting of the gulf, in the darting to an aim.”
—Ralph Waldo Emerson (1803–1882)
