摘要: The electrical and magnetic characteristics of some rare earth orthoferrites (RFeO3, where R = Y, Ho & Er) have been discussed. These two suggest that such system can be categorized under multiferroic with different Curie Neel temperature. shows relaxation phenomenon temperature varies change in frequency. is the range 340–480°C, whereas about 370°C.
