Title: Dependence of magnetization dynamics on magnetostriction in NiFe alloys
Published: December 23, 2005
Abstract: We present a quantitative, systematic study of the effect of magnetostriction on the dynamical properties in NiFe alloys. Both the ferromagnetic resonance frequency and the damping times are correlated to the magnetostriction. In addition, we find that the Gilbert damping parameter varies by more than 100% over the range of Ni percentage tested (61.9%-86.7%).
