摘要

This work reports studies performed in the superconducting compound F e S e (0.5) T e (0.5) under high pressure. Changes were observed in the transition temperature, superconducting critical fields, anomalous variations in the Meissner fraction, and in Ginzburg Landau parameters. The superconducting properties were calculated and compared using the Werthamer-Helfand-Hohenber approximation and Ginzburg-Landau theory. Hydrostatic pressure was produced from atmospheric to 823 MPa, the increment in the critical temperature was from 14.45 to 20.5 K at a rate of change about 0.0069 K/MPa.
