ON THE THEORETICAL-STUDY OF AN RF-SQUID OPERATION TAKING INTO ACCOUNT THE NOISE INFLUENCE

A possibility of Markov process technique application, namely the Fokker-Planck-Kolmogorov equation, for description of the RF-SQUID operation on the volt-current characteristic plateau taking into account the noise influence, in the case when CR(N) is a small parameter and C and R(N) are capacitance and resistance of the Josephson contact, respectively, has been described The theory developed here considers without any approximations the probabilistic processes taking place during the RF-SQUID operation given a maximum information about the behavior of such system. Moreover, it allows one to consider different noise sources and to study for each of them the influence on the operating regime.
