Abstract
Crossover near the fluctuation-induced first-order transition in superconductors is studied to first order in . We find that the effective exponent for the susceptibility of type-II systems falls from its value for the chargeless system to the mean-field value unity well before the first-order transition occurs. Although such effects are probably unobservable in real superconductors, these calculations may have some relevance to the nematic to smectic- transition in liquid crystals.
