“…(13) and (15), but this cannot be strong since the alloys are dilute. Thus, in analogy with the former result we can expect that 8y=k(C-C~) '~ (18) where 0 < a < 1 and k is a constant. Figure 21 shows the relation In 83, vs In 6C.…”

The magnetic properties of small-K superconducting In-Bi, In-Tl, In-Pb, Sn-Bi, and Sn-Sb alloys are investigated. The evaluation of the experiments is carried out in the framework of BCS and GLAG theory. At a critical alloy concentration a phase transition occurs, at which type I superconductivity goes over into type II. Comparing the results with Lifshitz's theory, it is found that the phase transition is of higher than second order. The contribution from the nonanalytical part of the concentration dependence of the electronic specific heat coefficient is 0.63-0.77, and thus the order of the phase transition increases by this amount.

The phase transition "type I to type II supercoaductivity" was irtvestigated theoretically by thermodynamic methods in the framework of the GLAG formalism. The conditions of the forming of the vortex lattice structure were determined and the features of the transition describe& It was shown that the order parameter becomes space depeadent in a periodic way during the phase transition. The critical value of the GL parameter and the range of the wave number belonging to the magnetic vortices which appear at the transition were given.
