Abstract

Muon spin rotation measurements were performed to deduce the magnetic penetration depth λ and vortex core radius ρv in the mixed state of YNi2B2C for Hc1≪H≥0.7 Hc2. A preliminary analysis based on the modified London model shows that ρv decreases steeply with increasing H, while λ increases linearly in H. Results also shows that the vortex core radius ρv shrinks with increasing field and subsequently levels off at higher fields. These indicate the need to reconsider the conventional rigid normal electron core picture by taking account of vortex-vortex interaction mediated by delocalized quasi particles.
