Critical magnetic fields of superconducting tungsten
The thermodynamic critical field curve of a superconducting tungsten specimen with resistivity ratio 7,500 has been measured as a function of temperature down to 3 m K (1 m K - 10-3 oK). From the raw data the critical field H0 at T = 0 is found to be 1.14·1 ± .007 G, and the zero field transition …

Superconducting critical field measurements in cerium doped lead between 4.1 degrees and 1.8 degrees Kelvin
Ballistic measurements were made of the critical magnetic fields of superconducting. cylinders of cerium-doped lead. Within the accuracy of our measurements, the introduction of the paramagnetic impurity, cerium, in lead has no effect other than a slight broadening of the transition. The samples, …
