(a) Temperature dependence of magnetic moment, measured for Fe0.975Cu0.025Te0.66Se0.34 in the vicinity and above Tc, under an applied hydrostatic pressure of 10 kbar, shown for selected magnetic fields for H || c-axis. Inset shows raw magnetic data for all magnetic fields. (b) Temperature dependence of the upper critical field, for H || c-axis, for Fe0.975Cu0.025Te0.66Se0.34 under applied hydrostatic pressure of 10 kbar, and for Fe0.99Te0.66Se0.34 under ambient pressure and hydrostatic pressure of 9.8 kbar.
