论文摘要
已经研究了稀土离子（r = er^{3+}，tb^{3+}）具有强旋轨耦合对介电性能的强旋轨耦合以及在rmn_2o_5多模拟rmn_2O_2的局部极相分离结构域引起的电偏振。发现这些参数与GDMN_2O_5中研究的参数有定性区分，其中gd ^{3+} ion在地面 ^8S_ {7/2}状态中的状态与晶格较弱地界定。结果表明，在Mn^{3+}和Mn^{4+}离子子系统中形成的极相分离域的性质大大取决于存在这些域的晶体场值。
The effect of rare-earth ions (R = Er^{3+}, Tb^{3+}) with strong spin-orbit coupling on the dielectric properties and the electric polarization induced by local polar phase separation domains in RMn_2O_5 multiferroics has been studied. These parameters were found to be qualitatively distinguished from those studied before in GdMn_2O_5, in which Gd^{3+} ion in the ground ^8S_{7/2} state is weakly bounded with the lattice. It is shown that the properties of the polar phase separation domains, which form in the subsystem of Mn^{3+} and Mn^{4+} ions, are substantially dependent on the values of crystal fields, in which these domains exist.
