Abstract

The carbon nanotubes (CNTs) doped MgB2 bulks were sintered in the 5 T pulsed magnetic field at 800 Â°C for 30 min. The critical temperature (Tc) is 36.3 K, a little higher than that of the bulks sintered without magnetic field, 35.7 K. The critical current density (Jc) shows anisotropy in high measurement magnetic field. The Jc at 20 K increase in high field region when the measurement magnetic field is perpendicular to the sintering magnetic field.
