text: # Morin transition
  
  The Morin transition (also known as a spin-flop transition) is a magnetic phase transition in $α-Fe_2O_3$ hematite where the antiferromagnetic ordering is reorganized from being aligned perpendicular to the c-axis to be aligned parallel to the c-axis below $T_M.$
  
  $T_M$ = 260K for $Fe^{3+}$ in $α-Fe_2O_3.$
  
  A change in magnetic properties takes place at the Morin transition temperature.
