Fluctuation Heat Capacity in Superconducting Thin Films of Amorphous BiSb
Abstract
With a resolution of 10-10 J/°K the fluctuation heat capacity has been observed near Tc in thin films of Bi0.4Sb0.6. No indication of peaking was seen in the heat capacity near Tc. The heat-capacity transition when compared with the corrected resistivity transition is found to have approximately twice the width. This width is 3 times that predicted by Ferrell.
