衬底温度对Ba2FeMoO6薄膜生长的影响及磁性质研究
Study on Magnetic Properties and Influence of Substrate Temperature on the Growth of Ba2FeMoO6 Thin Films
摘要
Abstract
By pulsed laser deposition, double perovskite oxide Ba2FeMoO6 ( BFMO) thin films with thickness of 100 nm was grown on SrTiO3 (100) single crystal substrates at temperature of 700 ℃ , 800 ℃, 900 ℃. The target was fabricated by sol-gel materials. The crystal structure, surface morphology and magnetic properties were characterized by XRD, AFM and VSM respectively. The results showed that the BFMO films grown at 900 ℃ display c-axis preferred orientation and the film quality is the best. The hysterisis loops showed that all the samples are ferromagnetic. The molecular magnetic moment increases as the substrate temperature increasing, and the data irregular changing area is at ranges of 700 ℃ to 800 ℃, but the data at the ranges of 800 ℃ to 900℃ is not evident.关键词
