Abstract
High current densities were measured for a 66‐μm‐thick sputter‐deposited Nb12Al3Ge superconductor in magnetic fields from 100 to 210 kOe. Critical currents at 4.2°K were 2.5×105 A/cm2 at 100 kOe, 1.3×105 A/cm2 at 150 kOe, 2.6×104 A/cm2 at 200 kOe, and 1.5×104 A/cm2 at 210 kOe. The current densities were comparable to current densities reported for Nb3Sn and V3Ga. The deposit was made at a rate of 1 μm/min and heat treated 20 days at 750°C prior to the current density measurements.This publication has 6 references indexed in Scilit:
