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.
