Transport and magnetic measurements on UPt3

Abstract

Experiments on the normal phase of UPt₃ show a large positive magnetoresistivity, almost temperature‐independent, linear in field, and a positive thermoelectric power which is not linear in temperature as T→0. The superconducting phase is characterized by a high thermal conductivity with a strong T² term, by a coherence length smaller than the mean free path, and by lower and upper critical fields H⁽⁰⁾c₁∼60 Oe and Hc₂(0)∼26 kOe.
