论文摘要
GDCR3（BO3）4单晶的磁性特性的综合研究已经进行。已经确定了铬子系统中内内和链交换相互作用的积分，并且已经估计了CR-GD交换相互作用的强度。估计了gdcr3（BO3）4的交换场和有效磁各向异性场的值。已经检测到了实验的纵向几何形状中A轴的电偏振。已经发现了电偏振与研究化合物的磁化的相关性。已经发现了磁序状态中的自旋逆转相变。对于沿任何晶体学方向应用的外部磁场的过渡，过渡场都存在，并且过渡场弱取决于该场的方向。已经讨论了自旋抗衡相变的性质。已经构建了磁相图并为低场和高场相构建了自旋构型。
Comprehensive studies of magnetic properties of GdCr3(BO3)4 single crystal have been carried out. The integrals of intrachain and interchain exchange interactions in the chromium subsystem have been determined and the strength of Cr-Gd exchange interaction has been estimated. The values of the exchange field and the effective magnetic anisotropy field of GdCr3(BO3)4 have been estimated. The electric polarization along the a axis in the longitudinal geometry of the experiment has been detected. Correlations between the electric polarization and the magnetization of the studied compound have been found. The spin-reorientation phase transition in the magnetically ordered state has been found. This transition exists for the external magnetic field applied along any crystallographic direction and the transition field depends weakly on the direction of the field. The nature of the spin-reorientation phase transition has been discussed. Magnetic phase diagram has been constructed and spin configurations for the low-field and high-field phases have been proposed.
