A. Gerber et al., SUPERCONDUCTIVITY IN THE METALLIC AMORPHOUS ALLOY ZR41.2TI13.8CU12.5NI10BE22.5, Physica. C, Superconductivity, 275(3-4), 1997, pp. 333-336
We report an observation of the superconducting transition in the meta
llic amorphous alloy Zr41.2Ti13.8Cu12.5Ni10Be22.5. The resistive super
conducting transition temperature is 1.1 K and the temperature gradien
t of the upper critical field (-dH(c2)/dT)(Tc) is 2 T/K. Annealing of
the alloy leads to a reduction of T-c by 0.2 K and a decrease of H-c2
to (-dH(c2)/dT)(Tc) = 1 T/K.
