我们测量了几种混合稀土钼酸盐 Ln2xGd2(1−x)(MoO4)3 的线性和非线性磁化率,其中 Ln 是 Nd、Sm、Gd、Tb、Ho、Yb。我们得出的结论是,非线性光学特性的主要部分是由于 MoO4 四面体取向和 Mo-O 键超极化性。纯化合物 Ln2(MoO4)3 的外推线性和非线性极化率与 Yb、Tm 和 Er 钼酸铁的不稳定性一致。
We have measured the linear and nonlinear susceptibilities of several mixed rare earth molybdates Ln2xGd2(1−x)(MoO4)3, where Ln is Nd, Sm, Gd, Tb, Ho, Yb. We conclude that the major part of the nonlinear optical properties is due to the MoO4 tetrahedra orientation and to the Mo–O bond hyperpolarizability. Extrapolated linear and nonlinear polarizabilities of pure compounds Ln2(MoO4)3 agree with the instability of Yb, Tm, and Er ferroic molybdates.
