  • Abstract
    Ternary and quaternary A-15 type compounds, Nb3Al1-yMy(M=Be,B) and (Nb1-xTax)3Al1-yGey, were investigated in the composition range where the A-15 structure was stable. The superconducting critical temperatures of these compounds were measured as a function of composition (x and y), lattice constant, and condition of heat treatment. It was found that the critical temperature can be enhanced up to near 20 K by substituting Al for the quest elements in a stoichiometric compound Nb3Al. Magnetic field dependences of the critical current density were also discussed for as-cast and aged samples.
