Thermoelectric power and asymmetry of point-contact spectra of NdCu

The temperature-dependent thermopower SðTÞ of NdCu has been measured in the temperature range from 4.2 to 300 K. We have studied the asymmetry of point-contact (PC) spectra of heterocontacts NdCu-Cu and compared with measurements of thermopower on bulk NdCu. The comparison shows the possibility of providing a valuable information about the electronic transport properties for this compound by using PC spectroscopy technique.
