Abstract

To understand possible interactions between magnetic and electric order parameters of Ni doped SrxBa1-xNb2O6, Ni doped Sr0.5Ba0.5Nb2O6 (SBN50) and Sr0.4 Ba0.6 Nb2 O6 (SBN40) are synthesized and investigated. Synthesis has been carried out via ceramic route. The paper reports the synthesis, crystal structure, dielectric properties, PE hysteresis loops, M-H hysteresis loops and magneto-capacitance of the Ni doped SBN compositions. All the compositions are observed to exhibit a useful value of magneto-capacitance, especially at frequencies less than 10 kHz.
