Abstract

MgB2 tapes with organic rare-earth salt additions were prepared by the in situ powder-in-tube processing method. Compared to the undoped tapes, the transport Jc are greatly improved by organic rare-earth salt doping. In addition, magnetization measurements showed an enhancement of flux pinning. Organic rare-earth salt doping not only enhances the upper critical field by increasing electron scattering, but also introduces precipitates and structural defects to improve the flux pinning. The results suggest that organic rare-earth salt has to be considered as a promising dopant for enhancing the current capacity of MgB2 conductors.
