Pulsed regime of a spin-injection oscillator

A spin-injection oscillator in the pulsed regime is studied for the first time at different time parameters of current pulses using an opto-acoustic transducer in the absence of chopper. The reciprocity principle is violated when the direction of current in the pulse is reversed in the pulsed regime...

Description
Summary:A spin-injection oscillator in the pulsed regime is studied for the first time at different time parameters of current pulses using an opto-acoustic transducer in the absence of chopper. The reciprocity principle is violated when the direction of current in the pulse is reversed in the pulsed regime of the terahertz generation. The radiation signal of the spin-injection emitter is proportional to the number of charges that are injected by a current pulse and does not depend on the energy that is released in the presence of the pulsed current flow.
