从单轴各向异性、交换各向异性、外应力三方面出发,根据Stoner-Wohlfarth模型及能量极小值原理,主要研究了在单轴各向异性与交换各向异性垂直条件下,改变外应力的方向对铁磁/反铁磁体系交换偏置角度依赖关系的影响.数值计算表明改变外应力的方向,可以使体系在单稳态与双稳态之间转变,导致角度依赖关系发生显著变化. Based on the Stoner-Wohlfarth model and the principle of minimum energy, this paper focuses on three aspects: uniaxial anisotropy, exchange anisotropy and external stress. Under uniaxial anisotropy and exchange anisotropy, The dependence of stress on the angular dependence of the exchange bias of the ferromagnetic / antiferromagnetic system is shown in the numerical results, which show that changing the direction of the external stress can change the system between monostable and bistable state, which leads to significant angle dependency Variety.
