Abstract
We report a thorough analysis of the structural, magnetic properties of LaxBi1-xFeO3 (x = 0.0-0.4) bulk polycrystalline samples. XRD reveals that the orthorhombic phase becomes more prominent and Rhombohedral phase decreases from 92.4% to 58.39% as 'x' increases from 0.05 to 0.4. La doping significantly affects the magnetic ordering in this system by destructing the spin cycloid in BFO. A huge enhancement in Mr and HC even for x = 0.05 observed at 300 K indicates the presence of a strong magneto-crystalline anisotropy. © 2013 American Institute of Physics.
