Enhanced room temperature ferromagnetism in YMnO3-modified lead-free ferroelectric Bi0.5Na0.5TiO3 materials

The strongly enhanced room temperature ferromagnetism in Bi 0.5 Na 0.5 TiO 3 materials was obtained via modification of YMnO 3 as solid solutions. The weak ferromagnetism in pure Bi 0.5 Na 0.5 TiO 3 was changed to ferromagnetism and antiferromagnetic-like with increasing the concentration of YMnO 3...

Description
Summary:The strongly enhanced room temperature ferromagnetism in Bi 0.5 Na 0.5 TiO 3 materials was obtained via modification of YMnO 3 as solid solutions. The weak ferromagnetism in pure Bi 0.5 Na 0.5 TiO 3 was changed to ferromagnetism and antiferromagnetic-like with increasing the concentration of YMnO 3 addition. The maxima magnetic moment was estimated at around 28.4 memu/g for 9 mol.% YMnO 3 -modified Bi 0.5 Na 0.5 TiO 3 as a solid solution. The reduction of the optical bandgap energy from 3.18 eV to 2.01 eV was obtained via increasing YMnO 3 addition into host Bi 0.5 Na 0.5 TiO 3 crystal as solid solutions with amounts up to 9 mol.%. We suggested that the observation in the reduction of optical bandgap energy and great enhancement of the magnetic moment in YMnO 3 -modified Bi 0.5 Na 0.5 TiO 3 compounds were strongly related to the random distribution of Y and Mn cations into the host lattice of Bi 0.5 Na 0.5 TiO 3 crystals. We expected that our work will provide a simple way to integrate room temperature ferromagnetism into currently developed green ferroelectric materials.
