Показано, что введение дополнительных центров пиннинга без масштабного перекрытия потенциальных ям дефектов приводит к росту критического тока для колончатых и конических дефектов различного размера. В зависимости от величины внешнего магнитного поля относительный прирост критического тока образцов варьируется от 4 до 47%. При этом более глубокие дефекты приводят к улучшению транспортных свойств сверхпроводника в более высоких полях. В более высоких магнитных полях в условиях слабого собственного пиннинга и сравнительно низкой анизотропии свойств ВТСП, повышение критического тока YBCO для колончатых дефектов в несколько раз ниже, чем для конических.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of the analysis of pinning mechanisms at the level of separate types of radiation defects during irradiation of exposed YBCO films on a metal substrate with iron ions. It is shown that the introduction of additional pinning centers without large-scale overlapping of potential defect wells leads to an increase in the critical current for columnar and conical defects of various sizes. Depending on the magnitude of the external magnetic field, the relative increase in the critical current of the samples varies from 4 to 47%. Deeper defects lead to better transport characteristics of the superconductor in higher fields. In higher magnetic fields under conditions of weak intrinsic pinning and relatively low anisotropy of superconducting properties, the increase in the critical current of YBCO for columnar defects is several times lower than that for conical defects.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ВТСП</kwd><kwd>критический ток</kwd><kwd>сила пиннинга</kwd><kwd>метод Монте-Карло</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HTS</kwd><kwd>critical current</kwd><kwd>pinning force</kwd><kwd>Monte Carlo method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 24-22-00398, https://rscf.ru/project/24-22-00398/.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Umezawa A. et al. // Phys.
