Abstract

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.
