Epitaxial LaSrMnO films with different thicknesses (9-90 nm) were deposited on SrTiO (0 0 1) substrates by pulsed laser deposition. The films have been investigated with respect to morpho-structural, magnetic, and magneto-transport properties, which have been proven to be thickness dependent. Magnetic contributions with different switching mechanisms were evidenced, depending on the perovskite film thickness. The Curie temperature increases with the film thickness. In addition, colossal magnetoresistance effects of up to 29% above room temperature were evidenced and discussed in respect to the magnetic behavior and film thickness.
通过脉冲激光沉积在SrTiO(0 0 1)衬底上制备了不同厚度（9 - 90纳米）的外延LaSrMnO薄膜。对这些薄膜的形貌结构、磁性和磁输运性质进行了研究，结果表明这些性质与薄膜厚度有关。根据钙钛矿薄膜的厚度，证实了具有不同开关机制的磁贡献。居里温度随薄膜厚度增加而升高。此外，还证实了室温以上高达29%的巨磁电阻效应，并就其磁行为和薄膜厚度进行了讨论。
