摘要
摘要由于磁能是在自旋域之间交换的,因此磁各向异性对于使用自旋电子器件的应用非常重要。铁钴在 d 块磁性材料中是独一无二的,因为它具有很强的自旋极化和高于室温的居里温度。在目前的日常电气应用中,尺寸缩小到纳米级范围。事实证明,薄膜技术改善了这些材料的基本特性。在玻璃基底上制备了不同厚度(如 10、30 和 50 纳米)的铁钴薄膜。在室温下,使用原子力显微镜(AFM)和磁力显微镜(VSM)技术分别对相应厚度的磁性能和表面进行了研究。磁性能随制备的薄膜的形貌性质而变化,所有厚度的薄膜都表现出磁滞回线,这证实了薄膜在室温下具有磁性。对于自旋阀装置,电极的选择有所不同;相反,可以使用厚度不同的相同磁性材料作为顶部和底部电极。
Investigation of Magnetic and Topography Properties for Fe50Co50 Various Thicknesses of Thin Film Grown on Glass Substrate by Using UHV RF Magnetron Sputtering
Since magnetic energy is exchanged across spin domains, magnetic anisotropy is important for applications using spintronic devices. FeCo is unique among d-block magnetic materials because of its strong spin polarization and higher-than-room-temperature of Curie temperature. In current day-to-day electrical applications, dimensions shrink down to the nanoscale range. It has been demonstrated that the thin film technique improves these materials’ basic characteristics. The FeCo thin film was prepared on a glass substrate with various thicknesses such as 10, 30, and 50 nm. The magnetic properties and surface were investigated to corresponding thicknesses at room temperature by using the AFM and VSM techniques, respectively. The magnetic properties varied by the topography nature of the prepared thin films and all the thickness films exhibited the hysteresis loop that confirmed that thin film has a magnetic nature at room temperature. For spin valve devices, electrode preferences differ; instead, the same magnetic material with varying thicknesses may be used as top and bottom electrodes.
