Abstract

In this paper, the authors investigated the dynamic magnetic response of submicron elliptical Ni₈₀Fe₂₀ thin film elements by using micromagnetic modeling. It was found that coherent rotation and magnetization ringing in Ni₈₀Fe₂₀ elements can be controlled by adjusting the axis-ratio of the ellipse, the thickness, and the angle of the magnetic field pulse. Further studies indicate that uniformity in the distribution of the magnetization is improved by reducing the length of the short axis and reducing the thickness of the thin film. These changes effectively suppress the magnetization ringing.
