| Research Abstract |
To fabricate rare-earth (RE) based high-Tc superconducting (RE123) films with high critical current density (Jc) under magnetic fields at 77 K, nanorods as columnar defects were introduced into the RE123 films. Critical current properties depended on Ts, and the relationship between Jc properties and morphology of nanorods were clarified. The Ts dependences of Jc properties were different according to the composition of the superconducting matrix. Moreover, Ts-independent Jc properties were achieved by the mixture of two different types of RE as the RE123 matrix using nanorod-doped RE123 films.
