Morin transition

The Morin transition (also known as a spin-flip 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 being aligned parallel to the c-axis below T_M.

T_M = 260 K for Fe³⁺ in α-Fe₂O₃.

A change in magnetic properties takes place at the Morin transition temperature.

• Verwey transition – Low-temperature phase transition in magnetite
• Ferromagnetism – Mechanism by which materials form into and are attracted to magnets
• Antiferromagnetism – Regular pattern of magnetic moment ordering
• Paramagnetism – Weak, attractive magnetism possessed by most elements and some compounds
• Néel temperature – Temperature above which magnetic properties changePages displaying short descriptions of redirect targets
