比较研究了在（100）取向MgO和SrTiO3（STO）衬底上沉积的磁铁矿薄膜的微观结构和磁性能。通过X射线衍射分析和拉曼光谱测量证实了应变高质量Fe 3 O 4薄膜的生长。两种薄膜的表面形貌和磁性能有明显的不同。此外，在STO上的薄膜中观察到带状磁畴结构。衬底诱导的应变被认为是负责这些观察，这显着影响的磁各向异性和磁耦合在反相边界的薄膜。(C)2008年美国物理研究所。
A comparable study of the microstructure and magnetic properties was performed for magnetite films deposited on (100)-oriented MgO and SrTiO3 (STO) substrates. The growth of strained high quality Fe3O4 films was confirmed by x-ray diffraction analysis and Raman spectroscopy measurements. The surface morphology and magnetic properties of the two films were found to be obviously different. Moreover, a stripelike magnetic domain structure was observed in the film on STO. Substrate-induced strain is believed to be responsible for these observations, which significantly affects the magnetic anisotropy and the magnetic coupling at the antiphase boundaries in the films.
