| In a mixed state for a type-II superconductor, the movement of vortices and changes in the magnetic field lead to the generation of Joule heat and a temperature gradient, $\nabla T$, within the superconductor. A thermoelectric current due to $\nabla T$ can generate hot spots and thermal fluctuations within a sample and consequently affect its ability to carry a superconducting current. To investigate the thermal effects on superconductivity, a model accounting for thermal effects is needed to address the dissipation of superconductivity more completely. In this talk, we analyzed a thermoelectric model for superconductors based on the time dependent Ginzburg-Landau(TDGL) theory, the principles of nonequilibrium thermodynamics and Landau theory of phase transitions. This model is a simplified version of the equations for thermoelastic superconductors derived by S. A. Zhou and K. Miya and by G. Maugin. |
