Isavnin A.G. STRENGTHENING OF STOCHASTIC RESONANCE EFFECT IN SUPERPARAMAGNETIC PARTICLES WITH HELP OF ADDITIONAL CONSTANT MAGNETIC FIELDThe phenomenon of stochastic resonance is researched theoretically for system of onedomain magnetic particles with single axis magnetic anisotropy in conditions of additional constant magnetic field application athwart to light axis. The calculations are made in frames of theory of two conditions for weak outside periodical signal. Temperature dependences of complex magnetic receptivity, signal attitude to noise and phase shift between incoming and outcoming signal at different meaning of constant field intensity are got in this article. It is shown that presence of such field leads to increase of system response on weak radio-frequency field at conditions of stochastic resonance.
