Point-contact spectra of PrNi5 in thermal regime: comparison with theory

Point-contact spectra of PrNi5, measured in thermal regime of electron transit, are compared with theoreticlal predictions. The thermal regime in PrNi5 arises from the interaction between the conduction electrons and magnetic excitons, i.e. the nonphonon mechanism of inducting the thermal regime is realized. The coincidence of experimental curves with teoretically predicted ones indicates that it is possible to obtain from the point-contact spectra, by means of calculation, the information on the transport function of interaction between electrons and quasi-particles in metals
