Analysis of Ferroelectric, Dielectric and Magnetic Properties of GdFeO3 Nanoparticles

In the present work, the chemical co-precipitation method has successfully been employed in the preparation of GdFeO3 nanoparticles. Prepared samples have been sintered at different temperatures in order to investigate their structural changes using XRD, SEM, and FTIR. P-E hysteresis loops have been measured at various sintering temperatures to understand the grain size effects on ferroelectric properties. From the XRD profile, we have optimized the sintering temperature by comparing this data with JCPDS data. For the temperature optimized sample, we have measured M-H hysteresis loops at 20 K and 300 K to understand its magnetic properties and also dielectric properties, which were measured from room temperatures to 600 degrees C as function of frequency. The present work has been undertaken to determine their suitability for further development as multifunctional materials.
