Reentrant superconducting resistive

Fig. 6. Resistance-vs.-temperature curves of a GdMO(,Sg sample for different values of the applied magnetic field, indicating near-reentrant superconductivity i.e. reentrant behaviour at finite field only (nominal composition...

Fig. 38. (a) Resistivity vs. temperature measured at different magnetic fields H on a polycrystalline HoNi2B2C sample. Tc is the superconducting transition temperature at H = 0. A near-reentrant behaviour occurs around a temperature Tn. (b) Temperature dependence of the specific heat Cp of a HoNi2B2C single crystal (2 mm x 3 mm x 0.1 mm in size), measured at zero magnetic fiekL Above the main peak of Cp(T) at Tn. two additional features appear (marked by arrows).
