Observation of stochastic resonance in bistable electron-paramagnetic-resonance systems

Abstract

Evidence of noise-induced effects in electron-paramagnetic-resonance (EPR) experiments is reported. The first observation of a stochastic resonance phenomenon in an EPR system operating in bistable conditions has been obtained. Experimental results indicate unambiguous effects on the frequency and phase of the response of the modulated bistable system in the presence of noise. Possible new progressions in the treatment of both theoretical and experimental stochasic resonance phenomenon are perceived.
