Abstract The surface heat transfer coefficientα for In, Sn, and Pb films is obtained from the investigation of the hysteresis in the magnetic field-voltage characteristics of these films in He I and He II. This hysteresis is caused by the heating-induced formation of normal hotspots in the resistive state of the films. The experiments demonstrate the influence of the thermal boundary resistance and of the thermal conductivity of the substrate and helium bath on the hysteresis.
