Enhanced flux pinning of Bi-2223/Ar tapes with nano-MgO particles addition
Enhanced flux pinning of Bi-2223/Ar tapes with nano-MgO particles addition
For the purpose of producing flux pinning centers, nano-MgO particles have been introduced into (Bi,Pb)2)Sr2Ca2Cu3Ox silver-sheathed (hereafter: Bi-2223/Ag) tapes fabricated by the Rod-In-Tube (RIT) process. It is found that transport critical current density (Jc) of samples doped with nano-MgO particles is higher than that of undoped samples by a factor of 1.2 in zero applied field and about 1.4 in a magnetic field range from 0.1 to 1 T at 77 K. Well-dispersed MgO particles can be observed by SEM. These results indicate that the introduction of nano-MgO particles can effectively improve the flux pinning ability and has a little detrimental effect on the Bi-2223 superconducting matrix.

Abstract
For the purpose of producing flux pinning centers, nano-MgO particles have been introduced into (Bi,Pb)2)Sr2Ca2Cu3Ox silver-sheathed (hereafter: Bi-2223/Ag) tapes fabricated by the Rod-In-Tube (RIT) process. It is found that transport critical current density (Jc) of samples doped with nano-MgO particles is higher than that of undoped samples by a factor of 1.2 in zero applied field and about 1.4 in a magnetic field range from 0.1 to 1 T at 77 K. Well-dispersed MgO particles can be observed by SEM. These results indicate that the introduction of nano-MgO particles can effectively improve the flux pinning ability and has a little detrimental effect on the Bi-2223 superconducting matrix.
