Abstract

The magnetic field distribution in the vortex state of (formula presented) has been probed by muon spin rotation. The analysis based on the London model with nonlocal corrections shows that the vortex lattice has changed from hexagonal to square with increasing magnetic field H. At low fields the vortex core radius, (formula presented) decreases with increasing H much steeper than what is expected from the (formula presented) behavior of the Sommerfeld constant (formula presented) strongly suggesting that the anomaly in (formula presented) primarily arises from the quasiparticle excitations outside the vortex cores.
