Y-Ba-Cu-O is a promising high temperature superconductor material because of its good electrical and magnetic properties. However, large and complex bulks cannot be made directly, and joining is a good way to solve th...
We have fabricated the large single domain YBaCuO bulk superconductors by using multiseeding technique combined with composition gradient in the precursor. Obviously, the growth time can be shortened by multiseeding m...
