INFLUENCE OF MAGNETIC-FIELDS ON THE INTERNAL-FRICTION OF NI

The influence of static and synchronous magnetic fields on the magneto chemical damping of a pure Ni sample was investigated to check the val idity of Degaque's model of magnetomechanical damping. The experimenta l dependences were fitted using four parameters which were common to b oth 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 paramet ers such as the magnetostriction and magnetization vector of Ni.
