Abstract

A simplified model is used to construct the magnetic phase diagram of CuCrO2 as a function of magnetic field and easy-axis anisotropy. Neglecting the weak interactions between hexagonal layers, CuCrO2 is predicted to undergo transitions between three different 3-sublattice (SL) phases with increasing field: from a chiral, non-collinear phase that exhibits multiferroic behavior, to a collinear phase, to a non-chiral, non-collinear phase. The phase diagram also contains 1-SL, 4-SL, and 5-SL collinear phases, some of which may be accessible in the nonstoichiometric compound CuCrO 2+.
