Abstract
The magnetomechanical damping (MMD) and mechanical Barkhausen noise power ( MN) are due to stress induced irreversible jumps of non-180 degrees domain walls in magnetostrictive materials. The high-frequency component of MN pow er shows a strong correlation with the behaviors of MMD and magnetostrictio n, while the low-frequency component, only present in the magnetized state, varies like the maximum permeability and the magnetic Barkhausen signal.
