A micromagnetic study employing OOMMF1 simulator of magnetic switching wave propagation along magnetic data channels is presented. The optimization of the wave propagation as a function of geometry and physical parameters is investigated, which resulted in an order of magnitude increase in the depth of magnetic signal propagation. Unlike unoptimized rapidly decaying waves, the resulting wave stays practically the same throughout the channel, improving wave detection characteristics. When the in-plan dimensions of the channel are scaled proportionally, the optimized propagation length remains relatively constant. This indicates a possibility of the scalability in the data channel, which has significant technological applications.
