Temperature Dependence Of Energy Dissipation In Type I Superconductors

By Boboshko N. and Pinatti D.G.


Energy dissipation due to the movement of the magnetic flux in superconducting tin was studied by means of the torsion pendulum technique. The study was made as a function of the mean velocity of vortices, applied magnetic field and temperature. A phenomenological expression for the energy dissipation is proposed. This model explained our experimental results as well as these obtained previously by Houston and Smith. © 1978.269575578Houston, Smith, (1967) Phys.
