Investigation of the superconducting energy gap in the compound LuNi${}_2$B${}_2$C by the method of point contact spectroscopy: two-gap approximation

N. L. Bobrov, S. I. Beloborod'ko, L. V. Tyutrina +4

It is shown that the two-gap approximation is applicable for describing the $dV/dI(V)$ spectra of LuNi${}_2$B${}_2$C-Ag point contacts in a wide interval of temperatures. The value…
