Magnetoelectric (ME) laminates show higher ME coefficients than that of natural multiferroics (e.g. Cr2O3, BiTiO) by up to several orders of magnitude. Recent studies on bulk ME sensors using Fe85B5Si10 (Metglas) /polyvinylidene fluoride composite show a high ME voltage coefficient of 21V/cm·Oe at 20 Hz [1]. However, bulk sensors suffer from poor epoxy bonding, aging and difficulty of integration...
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...
