Effect of Ni doping on ferroelectric, dielectric and magneto dielectric properties of strontium barium niobate ceramics

Abstract

To understand possible interactions between magnetic and electric order parameters of Ni doped Sr_xBa_1-xNb₂O_6, Ni doped Sr_0.5Ba_0.5Nb₂O₆ (SBN50) and Sr_0.4 Ba_0.6 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.
