Abstract

Using magnetic, thermal and neutron measurements we show that Rb ₄Mn(MoO₄)₃ is a quasi-2D triangular Heisenberg antiferromagnet with easy-axis anisotropy and successive transitions bracketing an intermediate collinear phase. An accurate quantitative account of the phase diagram is achieved through Monte Carlo simulation of a spin Hamiltonian with easy-axis anisotropy D=0.22J.
