Abstract

We present measurements of critical currents and critical magnetic fields in cylindrical indium films. The most interesting result is that the ratio of the experimental critical current Ic1 to Silsbee's critical value Ic0 practically does not depend on temperature. This ratio was strongly dependent on the film thickness changing from Ic1 ≈ 0.18Ico for the film thickness d = 0.3μm to Ic1 ≈ 1.3Ico for d = 5.5μm. These results cannot be explained in the framework of the existing theoretical models.

    Different theoretical studies have also been done to improve the theory (see, for example, Ref. 13-18), but for our sufficiently thick films these corrections should not be important. It is well known fact that the Ginzburg-Landau theory provides a satisfactory quantitative agreement with experiments even outside the region of its formal applicability (see, for example, Ref. 19.Google Scholar

    A similar result was reported in the paper by N. E. Alekseevskii and M. N. Mikheeva,Sov. Phys.-JETP 11, 211 (1960) for a tin film with d=200 nm (see Fig. 3 in their paper). They used comparatively long current pulses, but on the other hand, these pulses were short enough to exclude overheating.Google Scholar

    The theoretical calculation ofI c2 is a very complicated problem and we know of only one publication on this subject (Ref. 32). This paper predicts decrease of theI c2/Ic0 ratio towards the critical temperature in contrast to the experimental data presented here (Fig. 9).Google Scholar
