采用Czochralski法生长了Li_(0.067)Na_(0.933)Tb(MoO_4)_2晶体,并测试了Li~+在NaTb(MoO_4)_2晶体中的有效分凝系数.由粉末X射线衍射数据计算了晶体的晶胞参数.室温下,采用消光法测试了Li_(0.063)Na_(0.933)Tb(MoO_4)_2晶体在532 nm、633 nm和1064 nm处的费尔德常数,分别为-293.6 rad·m~(-1)·T~(-1)、-200.5 rad·m~(-1)·T~(-1)和-68.6 rad·m~(-1)·T~(-1),与纯NaTb(MoO_4)_2相比,其费尔德常数均有所增加.结果表明,在1064 nm处Li_(0.067)Na_(0.933)Tb(MoO_4)_2晶体有较高的磁光优值.

Li_(0.067)Na_(0.933)Tb(MoO_4)_2 magneto-optical crystal was grown by the Czochralski method. The effective segregation coefficient of Li~+ in NaTb(MoO_4)_2 was measured. The lattice parameters of the crystal were determined by XRD data. Verdet constants of Li 0.067Na0.933Tb(MoO4)2 crystal at the wavelength 532 nm, 633 nm and 1064 nm were investigated by the extinction method at room temperature. They are -293.6 rad·m~(-1)·T~(-1),-200.5 rad·m~(-1)·T~(-1) and -68.6 rad·m~(-1)·T~(-1), respectively, and are larger than that of pure NaTb(MoO_4)_2 at corresponding wavelengths. The results showed that Li_(0.067)Na_(0.933)Tb(MoO_4)_2 has a larger magneto-optical figure of merit at 1064 nm wavelength.
