Abstract

A method of measuring critical temperatures from 4.2 to 20°K is described; it is based on a special new apparatus for measuring the magnetic permeability of samples and is accurate to 0.2°K. The measuring method is simple and gives reliable and reproducible results even if the amount of superconducting phase in the samples is under 0.5.10-4 cm3. In measuring alloys containing two or several superconducting phases, the transitional curves give characteristic steps; the temperatures of these steps correspond to the TK of the phases present. The method may also be used for the phase analysis of superconducting alloys.
