Room-temperature ferromagnetism of sol-gel-synthesized Sn1−x 57FexO2−(Delta) powders
ABSTRACT: We report unusual observations in the magnetic behavior of Sn1−x 57FexO2−(Delta) powders prepared by a sol-gel method. Mössbauer spectra showed three different sites for those irons in the SnO2 lattice. The samples seem to exhibit many sources of ferromagnetism, and the dominance of one of...
