摘要: Ion implantation at liquid helium temperatures is a new method of producing metastable alloys. The special features this alloying technique are illustrated by two selected examples dilute and concentrated alloys, respectively. Superconductors containing small amounts paramagnetic (3d)-impurities such asHgMn, PbMn andSnMn exhibit strong pair breaking effects. In the case ofSnMn Kondo effect observed. Concentrated alloys Pd Pd-noble metal with hydrogen (deuterium) only superconducting in very high concentration range, being unstable room temperature. Such concentrations can be achieved ion He-temperatures. transition temperature thus raised to maximum value 16.6 K aH/Pd 0.55 Cu0.45≃0.7 alloy.
