EFFECTS OF HEAT TREATMENT ON SUPERCONDUCTING PROPERTIES OF AMORPHOUS Mo-Si FILMS

Ⅰ. INTRODUCTION Recently, amorphous superconducting empirical rules, electronic structures and phonon spectrums are better understood. Amorphous superconductors, contrasted with other kind of superconductors which have the same critical temperature T, are characterized by very high critical field Hc. In addition, amorphous superconductors are, in general, ductile, flexible and possess high mechanical tensile strength. These characters arevery good for making high field superconductive magnets. Unfortunately the critical cur
