Resumo

Superconductivity is observed in an epitaxial metal film sandwich of Ag-Pd-Ag, with ${T}_{c}=2.15$ K, initially. Room-temperature storage caused ${T}_{c}$ to drop to 1.00 K after 180 days, and the ${T}_{c}$ decrease was accompanied by development of a resistivity minimum. The large orbital contribution to ${H}_{{c}^{2}}$ 70 kOe/K, is comparable to those found in high ${H}_{{c}^{2}}$ Chevrel-phase materials.
