They constructed the phase diagram for this material system ... in these material systems and to search for other superconducting materials in the “nickel family””.

Copper and Nickel form a substitutional solid solution over the complete range of possible compositions of the alloy. The equilibrium "phase diagram" opposite shows the dependence of the alloys ...

While both iron zirconide and nickel zirconide are not superconducting, the newly prepared mixtures are, exhibiting a “dome-shaped” phase diagram typical of so-called “unconventional ...
