Abstract (EN): We address the problem of the magnetoresistance of a disordered two-dimensional superconductor in the fluctuation regime above Tc. We extend the Maki-Thompson result to temperatures closer to Tc and to higher magnetic fields by considering the magnetic field dependence of the superconducting fluctuations. We also obtain the zero-field conductivity at all temperatures above Tc. Our results agree with Larkins theory in its range of validity but differ from tentative extensions of his theory to higher magnetic fields which have appeared in the literature. © 1985 The American Physical Society.
