Dielectric and Magnetic Properties of Bi$_{1-x }$Sm$_{x}$FeO$_{3}$ (0$\le $x$\le $1)

Multiferroic materials like BiFeO$_{3}$ (BFO) have recently gained worldwide attention due to their applications in nonvolatile memories, spintronics, sensors, and micro mechanical systems (MEMS). BiFeO$_{3}$ is a naturally occurring multiferroics, however, the large leakage current has hampered its practical applications. To circumvent this problem generally, substitution is carried out at Bi and Fe sites. We have doped samarium (Sm) at Bi-site in BFO. Thin films were grown on Pt/Ti/SiO$_{2}$ /Si substrates by spin coating method. XRD patterns showed well-grown perovskite structure with polycrystalline nature. Dielectric properties, leakage current, and magnetic properties were systematically studied. A correlation between these properties will be presented.
