Abstract

Experimental measurements of the superconducting-to-normal phase boundary for a Sierpenskigasket wire network are presented. The fractal phase-boundary curve, Tc(H), shows four orders of dilational invariance and is in excellent quantitative agreement with theoretical predictions. The fracton dimension, d», has also been measured and is found to be 1.35 0.02, consistent with the calculated value of 1.365 for the planar Sierpinski gasket.
