Abstract
The cutoff function of the nonlocal generalized London equation (NGLE) describing the mixed state in a d-wave superconductor is found from comparison with a numerically obtained solution of the quasiclassical Eilenberger equations. A good agreement between these models is reached if the argument of the cutoff function of NGLE is taken to be temperature and field dependent, decreasing strongly at low temperatures. At high temperatures the field dependence of this argument is nonmonotonic and shows a minimum at a field which depends on the temperature. This result agrees with the prediction of the Hao-Clem theory.
