Supraleitung aufgedampfter Bleischichten mit Zusatz von Gadolinium

摘要: The influence of the paramagnetic impurity gadolinium on superconducting properties lead has been studied. Both components were forced to form an alloy by condensing them simultaneously from vapour phase a substrate at low temperature. transition temperature (Tc) decreases linearly with increasing Gd content. ForTcvs. concentration measurements yielddTc/dc=− 2·102 °K. This result is discussed viewpoint theories byBaltensperger and bySuhl andMatthias, compared results other systems.
