Evidence for Magnetic-Field-Induced Reduction of the Fluctuation Dimensionality in Bulk Type II Superconductors Just Above the Upper Critical Field Hc2

  • R. R. Hake

Abstract

Figure 11 shows a schematic H-T phase diagram for a bulk type II superconductor. Below T c the well-known Meissner, mixed, and sheath states are shown. Outside the upper critical field curve H c2 (T) we have shown dots representing the presence of “fluctuation superconductivity” associated with short-lived Cooper pairs. Our previous work1–4 on fluctuation superconductivity in extremely “dirty” type II supercondùctors has been primarily concerned with the H-T region well outside the H c2 (T) curve. The present work† focuses on fluctuation effects close to H c2 .
