摘要：
The present work surveys literature data related to the study of iron-rhodium-based (Fe-Rh) alloys. The crystal, magnetic, and electronic properties of the FeRh alloy and FeRh-based materials in the form of both bulk, thin-film, and nano-structured objects are considered. Peculiarities of the first-order antiferromagnet-ferromagnet transition are analyzed, and various explanations of its nature are discussed. Different approaches to the preparation of the iron-rhodium-based alloys are reported; an analysis of the effect of heat treatment conditions on the properties of the material and their reproducibility in measuring the magnetocaloric properties is performed. Causes for the record values of the magnetocaloric effect (MCE) observed for the material are shown, and prospects of the application of this alloy in magnetic refrigeration technology, medicine, electronics, and magnetic data recording technology are discussed.
