Effect of stanum doping and heat treatment on Bi-Sr-Ca-Cu-O superconducting ceramics
The influence of Sn doping in calcium (Ca) and copper (Cu) sItes either temperature for 30 hours soaking time were studied For Sn-free sample. heat treatment improved the superconducting transition temperature, TC(RI)) from 100 K to 104 K, when the sintered sample was annealed at 820°C The highes...
