Investigations on Fe-doped strontium barium niobate, single phase ferroelectric and magnetodielectric compounds

Abstract

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