| 英文摘要 | Room-temperature ferromagnetism was obtained in SrSn0.5Co0.5O3 (SSCO) epitaxial film on SrTiO3 substrate by pulsed laser deposition, and the effects of oxygen pressure (PO2) on the microstructure, optical and magnetic properties were examined. An interesting hybrid epitaxial film embedded with polycrystalline SSCO and SrCoOx nanoparticles was observed. The Increase of PO2 relaxed the film/substrate compressive strain, promoted the growth of crystallites and reduced the optical band gap (from 2.43 to 1.68 eV). The SSCO film deposited at 0.1 Pa exhibited good ferromagnetism at 100-300 K, while the ferromagnetism in the film with higher and lower oxygen pressure (1 Pa and 10(-4) Pa) was weak. [GRAPHICS] IMPACT STATEMENT Room-temperature ferromagnetism and tunable optical band gap (2.34-1.68eV) were demonstrated in Co-doped SrSnO3 thin film grown on SrTiO3 single-crystal substrate by pulsed laser deposition with varying oxygen pressure. |
