Spin-thermo-electronic oscillator based on inverse giant magnetoresistance
arXiv:1101.5351 · doi:10.1063/1.3686735
Abstract
A spin-thermo-electronic valve with the free layer of exchange-spring type and inverse magnetoresistance is investigated. The structure has S-shaped current-voltage characteristics and can exhibit spontaneous oscillations when integrated with a conventional capacitor within a resonator circuit. The frequency of the oscillations can be controlled from essentially dc to the GHz range by the circuit capacitance.
