Andreev-reflection spectra of superconducting-normal contacts with show a continuous increase of the superconducting order parameter at the antiferromagnetic phase transition K without re-entrant behaviour below the superconducting critical temperature K. A change is found in the superconducting ground state at K (zero magnetic field), and the magnetic-field–temperature phase diagram corresponding to the two superconducting states is reconstructed.
