Continuous spin reorientation in antiferromagnetic films
J. J. Alonso, J. F. Fernandez
Abstract
We study anisotropic antiferromagnetic one-layer films with dipolar and nearest-neighbor exchange interactions. We obtain a unified phase diagram as a function of effective uniaxial De and quadrupolar C anisotropy constants. We study in some detail how spins reorient continuously below a temperature Ts as T and De vary.
