We report the observation and suppression of quantized spin wave modes in a microfabricated rectangular permalloy (Py) element. The Py element was located on a coplanar waveguide and was connected to a Cu wire. The quantized Damon-Eshbach spin wave and the perpendicular standing spin wave modes appeared in the resonance spectra for the Py elements. Those non-uniform magnetization dynamics were suppressed when the non-uniformity of the radio frequency magnetic field for the excitation was reduced by changing the design of the device structure.
