Improving YBa${}_2$Cu${}_3$O${}_{7-\delta }$ annealing times through a combining-temperatures route

R. F. Luccas, L. Gallo

The oxygenation process at constant temperature of YBa${}_2$Cu${}_3$O${}_{7-\delta }$ (YBCO) was systematically investigated in the temperature range from 300 ${}^o$C to 800 ${}^o$C. With this pur…
