Abstract

The temperature dependence of the cosϕ conductance in Sn-O-Sn Josephson tunnel junctions has been measured just below the critical temperature, Tc. From the resonant microwave response at the junction plasma frequency as the temperature is decreased from Tc it is deduced that the amplitude of the cosϕ term first increases from near zero to positive values and only at T / Tc≲0.96 attains values of order-1.
