采用磁化率、强磁场和电子自旋共振等方法研究了层状化合物mnps3的磁性能。温度和角依赖性是二维反铁磁体的特征。在ab平面上的主要交换作用估计为j /k=- 9.5±0.2 k。在tn =78 K以下的低温条件下，高磁场过程和AFMR测量显示了一个自旋-翻边跃迁，atHc=38.0 kOe。假设垂直于ab平面的单轴各向异性能量k =1.52±0.10×105erg/cm3，可以令人满意地解释这些现象。
Magnetic properties of a layered compound MnPS3were investigated by means of magnetic susceptibility, high field magnetization and electron spin resonance. Temperature and angular dependence of EPR line width are characteristic of 2D-antiferromagnet. The main exchange interaction in theab-plane is estimated to beJ/k=- 9.5±0.2 K. High field magnetization process and AFMR measurements at low temperatures belowTN=78 K showed a spin-flop transition atHc=38.0 kOe. They are satisfactorily explained by assuming the uniaxial anisotropy energyK=1.52±0.10×105erg/cm3perpendicular to theab-plane.
