Exploration on magnetic, dielectric and magnetodielectric properties of PNZT-strontium hexaferrite composites
Magnetodielectric composites xPb0.8Nd0.2(Zr0.52Ti0.48)O3-1-xSrFe12O19 (x = 0.50, 0.52, 0.54, 0.56, 0.58) have been reported. Structural phase analysis confirmed successful synthesis of reported ceramic composites. Magnetic hysteresis reveals magnetic ordering in prepared composites whereas micrographs strongly support dielectric permittivity. All prepared composites exhibit high values of dielectric constant. Strong magnetodielectric response (MDR) is observed in low frequency region which goes on decreasing with frequency, indicating Maxwell-Wagner interfacial phenomenon in the studied composites. The MDR extends to higher frequency range (>100 kHz) signifying strain mediated mechanical coupling between ferrite and dielectric phases which is calculated in terms of the coupling coefficient (γ).
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
