ANTIFERROMAGNETIC TO WEAKFERROMAGNETIC TRANSITION AND THE TEMPERATURE DEPENDENCE OF THE TRANSVERSE SUSCEPTIBILITY IN HEMATITE BELOW THE MORIN TRANSITION.

Abstract

The antiferromagnetic (AF) to weak ferromagnetic (WF) transition in hematite below the Morin transition induced by an applied magnetic field in the basal plane, was studied experimentally and theoretically. Assuming that the single ion anisotropy is given by K sin squared theta the transition was found to occur by a gradual rotation of the AF axis, from the trigonal axis to the basal plane. This behaviour explains the reported increase of the perpendicular susceptibility with increasing temperature below the Morin transition point. (Author)
