【摘要】 钡铁氧体（ＢａＦｅ１２Ｏ１９）垂直磁化膜可用作高密度磁记录介质。本文研究用低温ＲＦ磁控浅射法制备非晶薄膜，经晶化处理所得到的垂直磁化膜的饱和磁化强度Ｍｓ、矫顽力Ｈｃ及垂直磁各向异性常数Ｋｕｌ、Ｋｕ２与退火温度Ｔ的关系，并对所呈现出的变化规律作了简单解释。介绍了依据转矩曲线的形状来判断薄膜垂直性优劣的方法，从转矩曲线出发，探讨了影响薄膜磁各向异性的因素更多还原

【Abstract】 Ba ferrite perpendicular magnetized film may be used as a high density magnetic recording medium. These thin films were prepared by rf magnetron sputtering on low temperature substrate and annealing. In this paper, the relationship between the saturation magnetization M s coercive force H c perpendicular magnetic anisotropy constants and annealing temperatures were studied. The factors which influence on magnetic anisotropy were discussed.更多还原
