Superconducting properties of AuPb₃ and AuPb₂

The superconducting critical temperature of AuPb3 and AuPb2 has been measured as 4.40°K and 3.15°K, respectively. Data available on the superconducting properties of Pb filaments in an Au matrix indicate AuPb2 is readily formed at room temperature due to rapid diffusion of Au into Pb. © 1964.
