Abstract :
Large stresses can occur in the Permalloy films employed for bubble propagation and detection. In narrow lines and features anisotropic stress relaxation can lead to strong magnetic anisotropies. It is shown that these anisotropies can have a dominant influence on the magnetic behaviour of narrow lines and on the chevron sensor.
