Popis:	Measurements of the upper critical fieldB c2 of superconducting Nb/Cu multilayers with fractal and periodic stacking sequence are reported. A positive curvature of the perpendicular magnetic fieldB c2⊥ , i.e. an upward deviation towards low temperatures from the linearB c2⊥ (T) behavior of the WHH theory is observed. The temperature where this upturn occurs depends on the number of fractal scalesS n .
