Point-contact Andreev reflection spectroscopy of a magnetic superconductor Dy₀.₆Y₀.₄Rh₃.₈₅Ru₀.₁₅B₄
The Andreev reflection spectra dI/dV(V) of the magnetic superconductor Dy₀.6Y₀.₄Rh₃.₈₅Ru₀.₁₅B₄ have been
 investigated. Pronounced stimulation of superconductivity by an external magnetic field has been observed for
 the first time. The effect showed up as enhancement of the gap stru...

| description | The Andreev reflection spectra dI/dV(V) of the magnetic superconductor Dy₀.6Y₀.₄Rh₃.₈₅Ru₀.₁₅B₄ have been
investigated. Pronounced stimulation of superconductivity by an external magnetic field has been observed for
the first time. The effect showed up as enhancement of the gap structure (and hence the gap itself) in the spectra
and its shift towards higher voltages with an increasing field. In the intermediate fields the structure also behaved
strangely: instead of the usual smooth decrease with a grooving field, the gap features dropped abruptly near the
critical point Hc₂. Of interest is also the abnormally high relative gap value 2∆/kBTc ≈ 4 (as compared to conventional
singlet superconductors) which was found for some contacts from a comparison of experimental spectra
and the modified Blonder–Tinkham–Klapwiyk theory. We attribute the features revealed in the point-contact
spectroscopic investigations of Dy₀.6Y₀.₄Rh₃.₈₅Ru₀.₁₅B₄ in a magnetic field to the triplet-type Cooper pairing in
the compound because only in this case one can expect the stimulation of superconductivity in the stationary
magnetic fields up to ~ 0.7Hc₂.
