Proposal for piezoelectric-ferromagnet bilayer based microwave oscillators without any external magnetic field or spin transfer torque

To summarize, we proposed and simulated a nanomagnetic microwave oscillator that does not require any DC or r.f. magnetic field (unlike in conventional FMR), nor any spin torque current (unlike in STNO´s). The frequency of oscillation can be effectively tuned by DC voltage in the microwave domain. The fact that magnetic fields and currents are not needed can make it a much cheaper, denser and less power hungry alternative for future electromagnetic oscillator applications.
