Abstract: We have performed a magnetic study of a bulk metallic sample of Nb with critical temerature Tc=8.5 K. Magnetization measurement taken for magnetic fields greater than 1 kOe show a superconducting transition that becomes broader as the field is increased. The data are well described by lowest Landau level (LLL) fluctuation theory. A scaling analysis yields values for the supercondunting transition temperature under field Tc(H) which are consistent with Hc2(T). © 2004 Published by Elsevier B.V.
