Abstract

Systematic preparation of a series of bulk MgB2 samples of Mg1-x Alx (B1-y Cy)2, x=2% ; y = 0%,1%,2%, 3%, 4%,6%, 10%, were carried out on nano alumina MgB2 co-doped with nano carbon. Bulk MgB2 samples have prepared by standard solid-state reaction method, followed by ball milling. As the concentration of nano carbon doped MgB2 increases their resistivity increases accordingly, results the lowering of transition temperature, Tc. Resistivity shows the systematic decreases of transition temperature with nano alumina and nano carbon doped MgB2. Here, we report that co-doping play an important role in decreasing the lattice parameters. A systematical comparison of nano alumina and nano carbon doped MgB2 with structure; superconducting transition, resistivity and FWHM are discussed.

Key Words
