Magnetoresistance studies of homogenously disordered 3-dimensional NbN thin films

We present magnetoresistance studies on a series of homogenously disordered 3-dimensional NbN thin films with disorder ranging from the moderately clean limit (kFl~10.12) to the extremely dirty limit where the superconducting ground state is completely destroyed (kFl~0.42). We find that for samples with kFl >1, the magnetoresistance is positive up to 12T and as disorder increases it decays more slowly with temperature. On the other hand, for samples with kFl
