Auteurs : RBID : ISTEX:10909_1974_Article_BF00658884.pdfAbstract
Using a sensitive mutual inductance method, measurements of first- and second-order phase transitions in indium microcylinders (2.8–7.6 µm in diameter) have been made. Quantum oscillations in the supercooling field have been observed. The values of κSC(T/Tc)=κ1(T/Tc) derived fromHSC=HC3 have been corrected for both the temperature and the size dependence in the relationship betweenHc2 andHc3. The results for κ1(T/Tc) from the 7.6-µm sample then agree reasonably well with the temperature dependence of κ1 observed for niobium. However, for the smallest cylinders anomalously low values of κSC(T/Tc) were obtained nearTc. Very close to the transition temperature second-order (nonhysteretic) phase transitions have been observed and are interpreted in terms of the Ginzburg-Landau theory.
