| Due to their potential applications in spintronics, as well as their ferroelectric, magnetocaloric, and lasing properties, rare-earth orthoferrites (RFeO3) have recently seen a renewed surge of scientific interest. In line with this trend, the present work provides an overview of research on magnetic phase transitions in dysprosium orthoferrite (DyFeO3). Both spontaneous and field-induced transitions are investigated based on the evolution of the magnetic domain structure, induced by temperature variations and external magnetic fields applied in various configurations with respect to the crystallographic axes of the sample. Phenomenological models of these transitions are presented and analyzed, leading to the construction of phase diagrams that are compared with experimental results. |
