【 摘 要 】

The temperature- and field-dependences of the superfluid density rho(s) in the vortex state of a d-wave superconductor are calculated using a microscopic model in the quasiclassical approximation. We show that at temperatures below T(*)proportional toH, the linear T-dependence of rho(s) crosses over to a T-2-dependence differently from the behavior of the effective penetration depth, lambda(eff)(-2)(T). We point out that the expected dependences could be probed by a mutual-inductance-technique experiment.
