Abstract

Modelling of a RF magnetic field’s configuration near the flat coil face of the tunnel diode based single-layer flat-coil-oscillator (SFCO) has been done – that serves as a sensor in one of most of effective methods for study of superconducti-vity (the SFCO technique). Particularly, the distribution of the measuring magnetic field of flat coil is investigated. An analytical formula has been derived, which allows to determine the parallel and perpendicular to coil face components of the measuring RF magnetic field at any point near the coil. The results of calculations are aimed at an achievement of the optimum sensitivity of the SFCO technique during the experimental study of fine peculiarities of superconductivity that are important for understanding the phenomenon.
