Bubble translational velocity studies on ion implanted
have demonstrated that several discrete deflection angles for a given bubble diameter can be obtained between the bubble velocity, V⇒, and the direction of maximum field gradient, ∇⇒Hm, with one of the angles predominating. These angles are interpreted by a theory due to Slonczewski. These deflections can be suppressed by the application of a constant in‐plane magnetic field of magnitude greater than or equal to 110 Oe which stabilizes the two Bloch line magnetic bubble. An increase in bubble velocity is also observed when the in‐plane magnetic field is applied.
