Paper Abstract

Stability of magnetic domains is evaluated on TbFeCo by measuring the minimum magnetic domain width (Wmin). Domains are recorded by magnetic field modulation method. Smaller Wmin can be observed by the sample with lower Tb content and higher sputtering pressure of under-layer. This can be explained by the temperature dependency of magnetization (Ms) and coercivity (Hc) qualitatively. From these results, we conclude TbFeCo has capability to record 0.1 micrometers .
