摘要:
本文利用脉冲激光沉积技术在(001)取向的SrTiO3基片上制备了外延Eu0.5Ba0.5TiO3薄膜。我们研究了后退火、微结构、表面形貌以及磁性质之间的关系。X射线衍射和卢瑟福背散射谱结果说明Eu0.5Ba0.5TiO3薄膜具有立方结构且化学计量比与块材一致。同时还发现改变后退火温度可以有效的调控薄膜晶格常数、表面粗糙度以及饱和波尔磁子的大小。
Epitaxial Eu0.5Ba0.5TiO3 thin films were deposited on (001) SrTiO3 substrates by pulsed laser deposition. The correlation between post-annealing, microstructure, surface topography and magnetic property was investigated. X-ray diffraction and Rutherford backscattering spectrometry measurements show that Eu0.5Ba0.5TiO3 thin films have a cubic structure and are stoichiometric. The variation of lattice constant, roughness and bohr magneton are strongly correlated with the anneal temperature.
