Abstract

We have calculated dynamic susceptibility of patterned cobalt and Permalloy pillars with a diameter of 50 nm and different pillar heights using micromagnetic simulations. The resonance modes obtained from these simulations are compared to the results obtained from analytical solution of Kittel's equation for spheroids. We also compared directly to Kittel s equation with the simulation of cobalt spheroids.
