“…In addition to the possibility of additional pinning centers creation at low concentration of defects, the irradiation technique is attractive due to the fact that using an ion irradiation with energies of about 1−10 MeV it is possible to create defect concentrations that significantly change the critical current and critical temperature up to the complete loss of superconductivity. In a recent study [43] we have demonstrated a drastic drop of critical temperature and critical current under the irradiation of HTS composites with Cu ions with an energy of E = 6.3 MeV.…”

“…For the measurement, the samples were cut out in the form of circle with a diameter of 3 mm. Quality of the cut was tested using magneto-optical visualization (see [43] for further details). The local distribution of critical current was measured by the method of scanning Hall magnetometry.…”

The results of studying the effect of ion irradiation (Fe2+ E=5.6 MeV) in the modes of creating radiation defects and implantation on the critical current of high-temperature superconducting (HTS) composites are presented. An analysis was made of both the integral critical current obtained from measurements of the total magnetization of the samples and the local critical current determined from the data of scanning Hall magnetometry. It is shown that at the same ion fluence Phi=2·1013 cm-2, an increase in the critical current Jc is observed in the ion implantation regime, while in the regime of radiation defects, a slight drop in Jc is observed. This circumstance indicates an enhancement of pinning due to the additional magnetic interaction of Abrikosov vortices with magnetic ions implanted in the HTS layer. Keywords: high-temperature superconductor, irradiation, radiation defects, critical current, magnetization.

“…Помимо возможности создания дополнительных центров пиннинга при малых концентрациях дефектов, радиационное воздействие привлекательно тем, что, используя ионное облучение с энергиями порядка 1−10 МeV, можно создать концентрации дефектов, существенно изменяющие критический ток и критическую температуру вплоть до полной потери сверхпроводимости. Так, в недавней работе [43] нами было продемонстрировано радикальное падение критической температуры и критического тока при облучении ВТСП-композитов ионами Cu с энергией E = 6.3 МeV.…”
