Vortex core shrinkage in a two gap superconductor: Application to MgB2

  • 1. Institut fuer Theoretische Physik, Universitaet Tuebingen, Auf der Morgenstelle 14, D-72076 Tuebingen (Germany)

Description

As a model for the vortex core in MgB2 we study a two band model with a clean σ band and a dirty π band. We present calculations of the vortex core size in both bands as a function of temperature and show that there exists a Kramer-Pesch effect in both bands even though only one of the bands is in the clean limit. We present calculations for different π band diffusivities and coherence lengths
