Abstract
Andreev-reflection spectra of superconducting-normal contacts with HoN i2B2C show a continuous increase of the superconducting order paramete r at the antiferromagnetic phase transition T-N = 5 K without re-entra nt behaviour below the superconducting critical temperature T-c = 9 K. A change is found in the superconducting ground state at T-c = 6.5 K (zero magnetic held), and the magnetic-field-temperature phase diagra m corresponding to the two superconducting states is reconstructed.
