Abstract

The point-contact spectra of the iron-based compound KFe2As2 were analyzed according to the thermal regime theory. We have obtained the values of the residual resistivity, the Lorentz number, and the electron mean free path in the contacts. It was shown that the most point-contact spectra can be described by this theory. The reasons for this behavior are discussed.
