多铁性磁体中的螺旋度、各向异性及其竞争：来自phase diagram的见解
Helicity, anisotropies and their competition in a multiferroic magnet: insight from the phase diagram
摘要：
受MnWO4复杂相图的启发，我们研究了各向异性次近邻海森堡模型中各向异性、磁场和螺旋度之间的竞争。除了有利于螺旋磁结构的两个竞争交换之外，该模型还具有双轴单离子各向异性。在实空间平均场近似下处理该模型，得到了不同场取向下包含各种无公度态和公度态的相图。讨论了MnWO4理论相图与实验相图的异同。
英文摘要：
Motivated by the complex phase diagram of MnWO4, we investigate competition between anisotropy, magnetic field, and helicity for the anisotropic next-nearest-neighbor Heisenberg model. Apart from two competing exchanges, which favor a spiral magnetic structure, the model features the bi-axial single-ion anisotropy. The model is treated in the real-space mean-field approximation and the phase diagram containing various incommensurate and commensurate states is obtained for different field orientations. We discuss similarities and differences of the theoretical phase diagram and the experimental diagram of MnWO4.
