ABSTRACT
An equivalent circuit obtained from microwave impedance and power data is proposed for a resonant tunneling diode. The four-element circuit consists of a series R and C in parallel with a nonlinear negative differential conductance -G, the combination in turn in series with a resistor r. The resistive cut-off frequency predicted by this model depends on both the RC and RG products. Detection at THz frequencies is also explained by the model.

    We show that the frequency of a magnetic tunnel junction (MTJ)-based spin torque oscillator (STO) can be doubled and the first harmonic entirely suppressed by orienting the free and fixed layer magnetizations in an antiparallel (AP) state. The angular dependence of the harmonics allows us to...
