Two superconducting states of HoNi2B2C as seen by Andreev reflection in point-contacts
UNSPECIFIED (1996) Two superconducting states of HoNi2B2C as seen by Andreev reflection in point-contacts. EUROPHYSICS LETTERS, 33 (6). pp. 483-488. ISSN 0295-5075Full text not available from this repository.
Andreev-reflection spectra of superconducting-normal contacts with HoNi2B2C show a continuous increase of the superconducting order parameter at the antiferromagnetic phase transition T-N = 5 K without re-entrant 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 field), and the magnetic-field-temperature phase diagram corresponding to the two superconducting states is reconstructed.
