Abstract
Fundamental operations in magneto-static spin wave devices of nucleation, propagation and inductive detection for a spin wave packets (magnetic solitons) are numerically studied by using micromagnetic simulations. The collective spin dynamics and device performances are compared for three different spin wave modes. Simulation results of the group velocity reasonably agree with the theoretical prediction under a thin film approximation. Structural and operational parameters are optimized so as to maximize the inductive output voltage V out . The practical V out of 0.052 mV/µm 2 is obtained at optimized parameters in a spin wave mode of magneto-static backward volume wave.
