Holmium induced enhanced functionality at room temperature and structural phase transition at high temperature in bismuth ferrite nanoparticles

Abstract

Ho-doped sample simultaneously exhibits high-coercivity and enhanced remnant magnetization with a polar <italic>R</italic>3<italic>c</italic> symmetry at room temperature. The onset of <italic>R</italic>3<italic>c</italic> to <italic>Pnma</italic> phase transition is observed at high temperatures in the Ho-doped samples.
