摘要

在超高密度记录介质中,磁化强度的热松弛是一个关键问题。热稳定性的典型特征是测量矫顽力的时间依赖性或测量磁化衰减作为饱和后反向场的函数。弛豫通常用磁黏度系数表示。黏度在矫顽力附近最大,热稳定系数较大时,在零场时黏度很小。我们最近报道了零场弛豫(ZFR)在各种薄膜中的测量,包括纵向介质、垂直介质和颗粒膜。测量结果是在零场中作为施加饱和反零场序列后获得的初始剩余磁化的函数进行的。

Zero field relaxation measurements in magnetic recording media
Thermal relaxation of the magnetization is a critical issue in ultra-high density recording media. The thermal stability is typically characterized by measuring the time dependence of the coercivity or by measuring the magnetization decay as a function of the reverse field after saturation. The relaxation is usually given in terms of a magnetic viscosity coefficient. The viscosity is usually greatest near the coercivity, and for large thermal stability factors, it is usually very small in zero applied field. We have recently reported zero field relaxation (ZFR) measurements in a variety of films, including longitudinal media, perpendicular media, and particulate films The measurements were made in zero field as a function of the initial remanent magnetization obtained after applying a saturation-reverse-zero field sequence.
