"We reported the room-temperature ferromagnetism in iron doped Bi0.5K0.5TiO3 nanocrystals. The reduction of band gap from 3.31 eV to 2.27 eV was obtained after introduction of iron to Bi0.5K0.5TiO3 with concentration up to 7 mol%. The first-principles density function theory (DFT) calculations indicate that the reduction of band gap is due to the presence of conduction bands of iron, and the ferromagnetism in iron-doped Bi0.5K0.5TiO3 samples was explained by the exchange splitting between spin subbands through crystal field theory. This method may provide an available way to get single-phase multiferroics and resolve the problem of the scarcity of single-phase multiferroics in nature."^^ . "2015-10" . "156" . .
