A METHOD OF MAKING A FLUX-TRAPPING SUPERCONDUCTIVE PLANE SUITABLE AS A MEMORY DEVIDE COMPRISING THE STEPS OF: (1) SUPPORTING A SOURCE OF TIN AND GERMANIUM IN A CONTAINER IN AN EVACUATED CHAMBER, (2) PREHEATING SAID CONTAINER TO A TEMPERATURE BELOW THE EVAPORATING TEMPERATURE OF EITHER TIN AND GERMANIUM, (3) SUDDENLY HEATING SAID CONTAINER TO A TEMPERATURE ABOVE THE EVAPORATING TEMPERATURES OF BOTH TIN AND GERMANIUM TO CAUSE EVAPORATION OF BOTH MATERIALS, (4) SIMULTANEOUSLY DEPOSITING BOTH EVAPORANTS ONTO AN INSULATED SUBSTRATE, (5) MAINTAINING SAID SUBSTRATE AT A TEMPERATURE TO EFFECT THE DEPOSITION OF BOTH EVAPORANTS, AND (6) ANNEALING THE THUS DEPOSITED LAYER OF TIN AND GERMANIUM TO FORM GLOBULES OF THE GERMANIUM WITHIN THE DEPOSITED PLANE.
