SmCo薄膜的共溅射制备及磁学性能研究
Studies on the Preparation and the Magnetic Property of SmCo/Cr Thin Films with Co-sputtering
【摘要】 采用磁控共溅射方法制备了非晶态的SmCo磁性薄膜,用振动样品磁强计(VSM)分析了薄膜的磁学性能,并通过原位后退火处理研究了其磁学性能。结果表明,在600℃下退火30分钟,SmCo薄膜样品的矫顽力升高,并且磁化取向有从面内转向垂直方向的趋势。
【Abstract】 Amorphous SmCo magnetic films were fabricated by magnetron co-sputtering method and the magnetic properties were measured by a vibrating sample magnetometer(VSM).Through in-site post annealing,the magnetic properties of the SmCo thin films were investigated.The results shows that after 600 ℃,30min annealing,the coercivity of SmCo films will be increased and the magnetic anisotropy will be changed from in-plane to normal-plane.
