Measurements of the current-voltage characteristics of a tunnel junction as a function of quasiparticle injection from a second tunnel junction are presented. Aluminum films (300 » thick) are studied from the transition temperature down to about 0.3

The low temperature thermal expansion of pure zinc and a dilute (40 ppm) zinc manganese alloy have been measured. Results confirm the oscillatory behavior of pure zinc and show the effect of a magnetic impurity. The pure zinc results can be accounted
