Popis: It is a serious problem that excess helium-ion etching greatly deceases superconducting transition temperature (Tc) and critical current density (Jc) of Bi1.6Pb0.4Sr2Ca2Cu3Ox. Thus, the influence of the etching on Tc and Jc has been investigated for the Bi oxide. A critical DOSE (Dc) to maintain high Tc above 100K is defined and evaluated. The Dc value is about 3.2×1017(ions/mm2) for the helium-ion etching.
