Upper critical field in the misfit layer compound (BiSe)(1.10)(NbSe2)

Magnetotransport measurements have been performed on the superconducting mi sfit layer compound (BiSe)(1.10)(NbSe2) with T-c = 2.36 K down to 100 mK an d in fields up to 1 Tesla in order to determine the upper critical field pe rpendicular as well as parallel to the layer structure. A temperature indep endent anisotropy has been determined. The temperature dependence of the up per critical field generally follows the Werthamer-Helfand-Hohenberg predic tion for classical type - II superconductors. Small discrepancies are ascri bed to the inhomogeneity in the sample.
