摘要：

Both temperature (T ) increase and/or application of an external magnetic field (H) are able to induce ferromagnetism in otherwise antiferromagnetic FeRh. We present a theory that allows us to predict H -T phase diagrams for FeRh, with a special emphasis on the canted antiferromagnetic phase. Both cases of in-plane and out-of-plane magnetic anisotropy in FeRh films are studied numerically, and the results of the simulations are compared with the results obtained via magneto-transport studies done in magnetic fields up to 34 T and x-ray magnetic circular dichroism measured at the Rh L2,3 and Fe K absorption edges in magnetic fields up to 17 T. The comparisons suggest examples of the simulated H -T phase diagrams that are most suitable to fit the case of FeRh.
