Abstract
Relaxor ferroelectrics Sr0.5Ba0.5Nb2O6 (SBN50) and Sr0.4Ba0.6Nb2O6 (SBN40), both pure and cobalt (Co) doped, have been synthesized and investigated to␣understand possible interaction between magnetic and electric order parameters. Synthesis was carried out via ceramic route. This paper reports the synthesis, crystal structure, dielectric properties, P–E hysteresis loops, M–H hysteresis loops, and magnetocapacitance (M c) of the Co-doped SBN compositions. All compositions were observed to exhibit useful values of M c, especially at frequencies less than 10 kHz.
