Physica C: Superconductivity and its applications
We have studied the dynamic properties of bubbles in a series of oxygen-annealed EuGaYIG films which have similar magnetic properties except for decreasing uniaxial anisotropy as a function of anneal time. The translational saturation velocity and skew angle of bubbles translated in a pulsed gradient field experiment increase as the anisotropy decreases. These results are in agreement with theoretical predictions of a Ku-1/2 dependence. We also observe that for a given anisotropy and bubble state (S=1), the skew angle decreases as the drive increases, in agreement with theory which predicts that if the velocity is saturated, drive and angle are inversely related.
