Abstract
The internal field distribution in the vortex state of is shown to be a sensitive measure of both the magnetic penetration depth and the vortex-core radius . The temperature dependence of is found to be weaker than in the conventional superconductor and much weaker than theoretical predictions for an isolated vortex. The effective vortex-core radius decreases sharply with increasing , whereas is found to be much stronger than in .
