Analysing the local magnetic field distribution obtained from the muSR spectra we identify regions of a Meissner state where the applied magnetic field is entirely expelled from the sample, an intermediate state where normal and Meissner states coexist, and a mixed state where a well-defined flux-line lattice is formed.
