| Research Abstract |
The MgB2 superconductor has been regarded as a promising material for superconducting magnet uses. In this study, we investigated the correlation between the critical current anisotropy and the microstructure of the ex situ powder-in-tube processed MgB2 tapes for obtaining a clue to some improvements in the critical current properties from the viewpoint of making use of the critical current anisotropy. The hard sheath material enhanced the critical current in high magnetic fields through the roll-induced texturing of the tape core, with respect to different orientation relations between the tape and the applied field. Additionally, results of using the slip casting method for fabricating textured powders are reported.
