Abstract
The measured point-contact (PC) spectra of the heterocontact between orient ed hexagonal single crystal of ferromagnetic NdNi5 and Cu in ballistic regi me are presented above and below Tc. We have observed maxima at characteris tic energies 1.5 meV and 4 meV which have the crystalline electric field or igin. The small shoulder at 9 meV and a broad maximum at about 18 meV are c onnected with phonons in NdNi5.
