Investigation of crystal structure and magnetic properties in Zn doped Bi0.84La0.16FeO3 ceramics at morphotropic phase boundary

In this investigation, we have studied the crystal structure and magnetic properties of Zn doped Bi0.84La0.16FeO3 (x = 0.02-0.1) ceramics at the morphotropic phase boundary of rhombohedral and orthorhombic phases. Rietveld refinement of the obtained XRD patterns and Raman spectroscopy confirm the presence of multiphases crystal structure of R3c rhombohedral and Pbam orthorhombic. Room temperature magnetic measurements showed weak ferromagnetic ordering and enhancement in magnetization and coercivity with dominating of orthorhombic phase. The isothermal structural transition from R3c to Pbam is caused for the decrease in magnetization and the increase in coercivity.
