Abstract:
We have performed a Zero-K Monte Carlo simulation for F/AF coupled systems of simple cubic structure. No combination of parameters, JF-AF/JF-F and JAF-AF/JF-F (JF-F, JAF-AF and JF-AF are exchange constant between F-F, AF-AF, and F-AF spins, respectively) ranging between 0.1 and 1 has been found, assuming Ku/JF-F=0.01 (Ku: uniaxial anisotropy coefficient), which gives unidirectional anisotropy in the sense that the energy exhibits 360° symmetry dependence on the F-magnetization direction. However, by assuming the existence of a plane in the AF-layer across which the AF-spins couple loosely with each other, it is demonstrated that a typical 360° symmetry anisotropy appears without assuming any AF-spin constraint in the plane.
