Abstract
Within the semi-classical approximation, we study the thermodynamic properties of the vortex state in d-wave superconductors when a magnetic field is applied parallel to the conducting plane, specially for low field and low temperature, H/Hc2 ≪ 1 and T/Tc ≪ 1. We find that the specific heat, the spin susceptibility, the superfluid density and the nuclear spin relaxation rate depend on the angle between the magnetic field and the a-axis and exhibit the scaling behavior in terms of T/√H. We predict also a substantial Hall superfluid density (i.e. the supercurrent component perpendicular to the vector potential Aω). Further the Hall superfluid density decreases slowly with increasing temperature.
