摘要：

The influence of static and synchronous magnetic fields on the magnetochemical damping of a pure Ni sample was investigated to check the validity of Degaque's model of magnetomechanical damping. The experimental dependences were fitted using four parameters which were common to both dependences. It was revealed that Degaque's model describes these dependences qualitatively very well. The values of the parameters were found to be consistent with appropriate values of microscopic parameters such as the magnetostriction and magnetization vector of Ni.
