Abstract: We report the near edge x-ray absorption fine structure (NEXAFS) and x-ray magnetic circular dichroism (XMCD) studies at the Mn L3,2 edge of pulsed laser deposited pristine thin films of multiferroic BiMn2 O5. These investigations are furthermore testified for BiMn2 O5 thin films irradiated through 200 MeV Ag15+ ions with fluence value 5× 1011 ions/ cm2. Though the pristine film is primarily antiferromagnetic in nature, irradiation induces ferrimagnetism in it. Element specific characterizations, NEXAFS and XMCD demonstrate the evolution of Mn2+ state piloting to magnetic signal associated with it. © 2010 American Institute of Physics.
