Temperature and compositional dependence of magnetic bubble properties of amorphous Gd-Co-Mo films
Abstract
It is shown that the temperature and compositional dependence of the magnetic bubble properties of amorphous Gd-Co-Mo sputtered films can be described satisfactorily by simple models based on mean field analysis of the experimental data. Using the fitting parameters obtained, bubble properties such as 4πMs, l, Q, and Hs (collapse field) are predicted as a function of temeprature for 1-, 0.5-, and 0.25-μm-diam bubbles. Optimum compositions for small temperature derivatives are suggested by this analysis. Some consideration of the dynamic properties for the present ternary films is also given.
