摘要

Over the last few years, researchers have been seeking novel oxide materials with room-temperature ferromagnetic properties for use in spintronics devices. In a recent work, we have reported room temperature ferromagnetic correlations in BaBiO3 nanoparticles which is non-magnetic in its bulk form. Here we have conducted a systematic study of the magnetic behavior by controlled Pb doping. We observe an increase in magnetic saturation for small Pb doping concentration (~ 1%), this is believed to be due to the strain magnetism induced by doping. Upon further increase in the doping concentration, the ferromagnetic behavior has been found diminished in a controlled manner, which indicates the dominance of non-magnetic ion distribution over strain magnetism.
