We address the possibility of non-magnetic doping induced magnetism, in Li-doped SnO 2 nanoparticles. The compounds have been prepared by solid-state route at equilibrium and were found to be crystallized in single rutile phase.

Description
Summary:We address the possibility of non-magnetic doping induced magnetism, in Li-doped SnO 2 nanoparticles. The compounds have been prepared by solid-state route at equilibrium and were found to be crystallized in single rutile phase. The magnetization measurements have shown that Li doping induces magnetism in SnO 2 for a particular range of Li concentration. However, for other Li concentrations, including pure SnO 2 , the samples exhibit diamagnetism. To investigate the possible origin of the induced magnetism, we have studied the variation of the magnetization as a function of the average nanoparticle radius. Possible scenarios for the appearance of magnetism in these compounds are discussed.
