Effect Of Magnetic Field On The Thermal Conductivity Of Single Crystal

ABSTRACT This research investigated the effect of magnetic field on the thermal conductivity of high temperature type II superconductors. The result suggested that the thermal conductivity of high temperature type II superconductor YBa2Cu3O7- decreases as the applied magnetic field increases at a given temperature. We also found out that the superconducting energy gap of YBa2Cu3O7- decreases in response to increasing temperature and applied magnetic field. At a critical temperature of about 100K, we noted a sharp decrease in the energy gap of the substance. This implies that, the supercondu…
