摘要：

The temperature dependence of electric voltage in a Bi-Sr-Ca-Cu-O film is measured for various electric currents and magnetic fields perpendicular and parallel to the film plane, in which the direction of the electric current is both perpendicular and parallel to the magnetic field. The thermally activated flux motion is deduced from the logarithmic dependence of voltage against l/T and the relation between the transition temperature and the Lorentz force. The relation between the activation energy, the transition temperature, the Lorentz force, and the volume to hop over energy barrier is discussed.
