  • Method for increasing the critical velocity of magnetic bubble propagation in magnetic materials
    Patent number: 4060798
    Abstract: The critical velocity at which magnetic bubbles can propagate within a matic material is increased by establishing an easy axis of magnetization within the material. This axis is either growth-induced or strain-induced. In one embodiment, the material has a curvature imparted to it which places it under a uniaxial strain and this induces the magnetic easy axis.
