Abstract

Domain wall (DW) oscillators have recently acquired a huge amount of research interest, due to their promising easy tunability along with the miniature single-layered structure. The output frequency control of DW oscillator through magnetic field and current has been studied in detail; but, there are issues yet to be addressed. Here, we propose several designs of DW oscillators and try to address some issues of control, output frequency and input power.
