The Superconductive Critical Magnetic Field of Beryllium
Robert J. Soulen, J H. Colwell, William E. Fogle
We have measured the temperature dependence of the superconductive critical magnetic field of several samples of beryllium from three different sources. The data were well represented by the BCS model of superconductivity. The values of Tc and Hc(O) were found to be sample dependent. for the purest sample studied, Tc=24.34 0.02 mK, Hc(O) = 107.7 0.2 T and (γ/V) = 329 1.3 ergs/cm3K2. By extrapolation of the data as a function of purity, it is inferred that the critical parameters for pure Be are: Tc = 24.44 mK, Hc(O) = 108.1 T and (γ/V) =330 ergs/cm3K2.
