Use of highhyphen;Tcsuperconductors for the determination of absolute thermoelectric power

摘要

The use of the recently discovered highhyphen;Tcsuperconductors for purposes of precision determination of the absolute thermoelectric power is illustrated on commercially available wires of copper and Nbhyphen;Ti. Highhyphen;Tcsuperconductors offer a wide range of temperatures where precision metrology can be carried out, and their unusually steep upper critical field allows for an accurate determination of the effect of magnetic field on the thermopower of test leads.
