Notes:
Abstract Low-field magnetic screening and breakdown fields have been measured in thick proximity-induced superconducting copper by means of dc magnetization and ac susceptibility in the temperature range 10 to 0.005 K. From the thickness and temperature dependence of the breakdown field the Cooper pair penetration depth in copper is obtained. This value isK N −1 =0.6/T μm, withT in kelvins. No saturation effects were observed in the screening length ρ, the breakdown fieldH b, or the supercooled fieldH sc down to the lowest temperatures.
