Abstract

The determination of in-plane magnetic penetration depth and vortex core radius in Y(Ni_1-xPt_x)₂B₂C by μSR was discussed. It was demonstrated by magnetic field dependence of the penetration depth, that quasiparticle excitations exist not only in the vortex cores but also their outside. It was found that the superconducting gap had changed from anisotropic to effectively isotropic after doping of Pt.
