Superconductivity in high-pressure synthesized pure and doped MgB2 compounds

P. Toulemonde, N. Musolino, H. L. Suo +1

Dense pure and doped (Mg1-xAx)B2 samples with A = Na, Ca, Cu, Ag, Zn and Al were synthesized at high pressure - high temperature in a multi anvils press (3.5-6 GPa, 900-1000C) for…
