Abstract
A peak in the resistance versus temperature measurements,just above T-c, ha s been observed in Nb/CuMn multilayers with a regular array of holes. The p eak is present in zero magnetic field and its height becomes smaller as the perpendicular field is increased. The presence of the peak could be relate d to the nonhomogeneity of the sample consistently giving an explanation fo r the upward curvature observed in the H-c2 versus temperature curve.
