Abstract
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.
