Abstract

Experimental results are presented of the influence of small static torsional deformations on the magnetomechanical damping in electrolytic nickel as a function of surface shear strain amplitude. The peak which appears in the undeformed state decreases and shifted towards higher amplitudes as a result of the deformation. Simultaneously, the peak becomes flatter, i.e., the magnetomechanical damping tends towards a constant value, which is interpreted as a limitation of the number of the irreversible Bloch‐wall jumps. These results are interpreted theoretically and the expression of the magnetomechanical damping as a function of the shear strain amplitude is established, including the effect of the deformation. A good correspondence between the theoretical and experimental results is found.
