Dynamic and static magnetic anisotropy in thin-film cobalt zirconium tantalum

Dynamic anisotropy of thin Permalloy films measured by use of angle-resolved pulsed inductive microwave magnetometry

“…The method of correcting for dragging was previously reported in detail. 15 As a check on the correction for dragging, we also performed measurements aligned to the easy axis where there should be no dragging effect, and find agreement within the error bars. Figure 3 shows the rotatable anisotropy as a function of inverse film thickness.…”

“…The data are already corrected for both the finite CPW width effect and the dragging effect. 7,15 The data from the three different CPW widths overlap at all angles of the easy axis, demonstrating that the correction for the effect of the finite width CPW is valid at all angles. Even though we are performing the measurements with a bias field that is at least four times the anisotropy of the film, the direction of the magnetization deviates slightly from the applied bias field direction.…”
