Effect of Al addition on the superconducting properties and microstructures of MgB2 tape prepared by PIT method
MgB2 tapes with Al addition were fabricated by powder in tube (PIT) method. The superconducting property and microstructure of Al doped MgB2 tapes were investigated with X-ray diffraction, optical microscopy and magnetic measurements. The Jc value of MgB2 tapes was increased with Al addition. The Jc-B curves show enhancement in Jc(B), which suggests that the microstructure and transport properties of MgB2 tapes have been improved with Al addition.
