Magneto-dielectric coupling in SmFeO3: A study on anomalous dielectric, conductivity, impedance at spin reorientation temperature

The SmFeO3, a family member of rare earth orthoferrite, is a potential candidate for future industrial (spintronics) applications due to highest spin reorientation temperature (453-483 K) among other RFeO3 members. There are ambiguous reports on high permittivity behavior of SmFeO3. In this report, the origin of high permittivity in SmFeO3 is attributed to microstructure rather than inherent material property of material. Ceramic pellets of...
