Abstract

Pb<subscript>0.5</subscript>La<subscript>0.5</subscript>FeO<subscript>3</subscript> has been synthesized by a single-step solution combustion method using sucrose as a fuel. The combustion-synthesized material was characterized by differential thermal analysis (DTA), magnetic measurements, powder X-ray diffraction and neutron diffraction. The crystal structure examined by the diffraction methods indicates that the material is single-phase, and crystallizes in an orthorhombic (space group, Pnma) structure. Similarly to parent LaFeO<subscript>3</subscript>, the lead doped compound showed canted antiferromagnetic behavior associated with an increase in magnetic moment. The changes in magnetic properties of the material are correlated to the changes in structural features resulting from the Rietveld structural refinement of the diffraction patterns.
