Abstract

Данная работа посвящена изучению кинетических свойств сверхпроводников на основе железа семейств 1111 и 122. Задачей работы было проведение анализа поведения различных кинетических коэффициентов с целью выявления общих особенностей температурных и концентрационных зависимостей этих коэффициентов в сверхпроводниках на основе железа различного состава. Для этого были описаны имеющиеся в литературе данные об электронном транспорте в нормальной фазе в исследуемых сверхпроводниках и проанализированы возможные причины изменения кинетических коэффициентов под действием легирования различного типа. На основании обобщения приведенных результатов выделены нерешенные на данный момент проблемы в области исследования электронного транспорта в рассматриваемых материалах и сформулированы цели дальнейших исследований, направленных на решение этих проблем. Также в работе описаны методики измерения температурных зависимостей четырёх основных кинетических коэффициентов, которые будут использованы при проведении в дальнейшем экспериментальных исследований электронного транспорта.

This work is devoted to the study of the kinetic properties of iron-based superconductors of families 1111 and 122. The objective of the work was to analyze the behavior of various kinetic coefficients in order to identify common features of the temperature and concentration dependences of these coefficients in iron-based superconductors of various compositions. For this, the literature data on the electronic transport in the normal phase in the studied superconductors were described and possible reasons for the change in the kinetic coefficients under the influence of doping of various types were analyzed. Based on a generalization of the above results, the currently unresolved problems in the field of electronic transport research in the materials under consideration are highlighted and the goals of further research aimed at solving these problems are formulated. The paper also describes methods for measuring the temperature dependences of the four main kinetic coefficients that will be used in further experimental studies of electron transport.
