Abstract
The internal field distribution in the vortex state of YBa2Cu3O6.60 is shown to be a sensitive measure of both the magnetic penetration dept h lambda(ab) and the vortex-core radius rho(0). The temperature depend ence of Po is found to bt weaker than in the conventional superconduct or NbSe2 and much weaker than theoretical predictions for an isolated vortex. The effective vortex-core radius decreases sharply with increa sing H, whereas lambda(ab)(H) is found to be much stronger than in NbS e2.
