Abstract

A high-pressure annealing technique has been used to convert an amorphous Nb-23.7 at.% Si alloy, prepared by sputtering, into the A15 phase alloy. X-ray diffraction examination of the alloy samples quenched to ambient conditions has shown that they are in an almost single-phased state with a lattice parameter of 0.5120 nm and a high degree of atomic ordering. An onset of superconductivity has been detected at 8.9 K and a temperature derivative of upper critical field is 14 kOe/K (MA/4π mK).
