Temperature dependencies of the upper critical field and the Ginzburg-Landau parameter for single-crystalline NbSe2

We present the results of magnetization measurements made on a NbSe2 single crystal for magnetic-field orientations both along and perpendicular to the c-axis of the crystal. The data were analyzed using a recently developed scaling procedure. We show that in the case of NbSe2, in addition to evaluating Hc2(T), the temperature dependence of the Ginzburg-Landau parameter may be extracted from the reversible-magnetization data. NbSe2, whose properties were extensively studied in the past, is used as a test case for the above-mentioned scaling procedure
