Abstract

Measurements have been made of the magnetic susceptibility of samples of superconducting granular aluminum with different metal volume fractions. The penetration depth, determined from the results below the transition temperature Tc, is found to diverge at the volume fraction where the discontinuity at Tc in heat capacity measurements disappears. The results near and above Tc have been interpreted in terms of both fluctuation and percolation models as showing effects of grain clustering. Possible evidence for the Kosterlitz-Thouless transition is discussed.
