Thermal Point-Contact Spectroscopy in UPt sub 3

The current--voltage characteristics of UPt sub 3 point contacts have been measured between 4-100K. The voltage dependence of the contact resistance at low temperatures resembles the temperature dependence of the resistance at zero bias voltage. These point-contact data are explained in terms of loc...

Description
Summary:The current--voltage characteristics of UPt sub 3 point contacts have been measured between 4-100K. The voltage dependence of the contact resistance at low temperatures resembles the temperature dependence of the resistance at zero bias voltage. These point-contact data are explained in terms of local Joule heating in the contact area. 18 ref.--AA
