Abstract

We report a magnetic thin film of single-nanosize ฮต-Fe2O3 in SiO2 matrix. The glass-film was prepared by sintering a silica coated iron oxide hydroxide on a quartz substrate in air. The glass-film consists of ฮต-Fe2O3 of 8.8 nm size, and its thickness was 570 nm (0.57 ฮผm) with a roughness of 10 nm (0.01 ฮผm). UV-vis spectrum showed that the glass-film has small absorbance of 0.043 at 500 nm. The magneto-optical effect was investigated, and Faraday ellipticity showed a magnetic hysteresis loop with a coercive field of 3.0 ยฑ 0.2 kOe. Furthermore, single-nanosize ฮต-Fe2O3 without silica was prepared as a reference sample, and ferroelectricity was observed. Therefore, the present thin glass-film consists of single-nanosize ferroelectric-ferromagnetic nanoparticles.
