论文摘要
Spin-5/2双molybdate寿命（MOO $ _4 $）$ _ 2 $的磁性特性以热容量，磁化率和中子粉末衍射技术为特征。与多效系统寿命（MOO $ _4 $）$ _ 2 $不同，它展示了两个连续的磁过渡，Life（Moo $ _4 $）$ _ 2 $仅在$ 〜23.8 k的情况下仅进行一次反铁磁过渡。密度功能理论计算证实了抗铁磁基态，并提供了相关交换偶联常数的数值估计。
The magnetic properties of the spin-5/2 double molybdate LiFe(MoO$_4$)$_2$ have been characterized by heat capacity, magnetic susceptibility, and neutron powder diffraction techniques. Unlike the multiferroic system LiFe(MoO$_4$)$_2$ which exhibits two successive magnetic transitions, LiFe(MoO$_4$)$_2$ undergoes only one antiferromagnetic transition at $T_N$ ~ 23.8 K. Its antiferromagnetic magnetic structure with the commensurate propagation vector k = (0, 0.5, 0) has been determined. Density functional theory calculations confirm the antiferromagnetic ground state and provide a numerical estimate of the relevant exchange coupling constants.
