Effect of substrate temperature on the growth of Nb3Sn film on Nb by multilayer sputtering

Md Nizam Sayeed, Uttar Pudasaini, Charles E. Reece +2

Nb3Sn films were fabricated by multilayer sequential sputtering on Nb at substrate temperatures ranging from room temperature to 250 °C. The multilayers were then annealed inside a…
