Magnetic Characteristics of Erbium Based Orthoferrites

The rare-earth orthoferrites are well known for demonstrating a spin reorientation phenomenon. We investigate the effects of Cr doping in the Fe sites in Erbium- based orthoferrite, ErFeO₃. Polycrystalline ErFe1-xCrxO3 samples were prepared by conventional solid state reaction method and their magnetic properties studies via vibrating sample magnetometry in the temperature range 50 K-300 K.
