一个简化的模型被用来构建作为一个功能的磁场和易轴各向异性的CuCrO 2的磁相图。忽略六方层之间的弱相互作用，预测CuCrO 2经历三个不同的3-亚晶格（SL）相之间的过渡与增加字段：从手性，非共线相，表现出多铁性行为，共线相，非手性，非共线相。相图还包含1-SL、4-SL和5-SL共线相，其中一些可以在非化学计量化合物CuCrO 2 +δ中获得。
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 CuCrO2+δ.
