superconducting transition

https://doi.org/10.1351/goldbook.S06137
A transition at the @C01402@, \(T_{\text{c}}\), below which the @R05315@ of electrical conductors becomes zero and @M03684@ is excluded. Examples: The transitions of Nb3Sn, Nb3Al and V3Si to superconductors (\(15\ \text{K} < T_{\text{c}} < 20\ \text{K}\)) and YBa2Cu3O7-x (\(x\approx 0.2\)) at \(90\ \text{K}\).
