description: This work is devoted to the analysis of the temperature dependences of the Nernst coefficient in high-temperature superconductors of the Y-Ba-Cu-O type. In the process of work, we studied samples with different calcium content.The first chapter of this paper contains a literature review on the features of this type of material as well as on the model of a narrow conductive band. Particular atten- tion is paid to the behavior of the Nernst coefficient in the Y-Ba-Cu-O system in the narrow band model. In addition, the effect of partial calcium replacement has been investigated by us.The second chapter describes the experimental methodology. In particular, an experimental setup is described that has a number of features aimed at increasing the recorded signal, this is due to the fact that the signal of the Nernst effect is very low and, in many cases, is less than the noise signal in order of magnitude. Particular at- tention is paid to the method of getting rid of noise signals that are even in the magnetic field. In addition, measures were taken to stabilize the temperature, which is important for the dynamic mode of measurement.The third chapter presents the experimental results. This chapter describes in detail the characteristics and differences of the samples under study, and also analyzesÂ the data from the study of the temperature dependences of the seebeck coefficient on the same samples, this is done because the totality of data from the analysis of the seebeck and Nernst coefficients makes it possible to determine the parameters of the band and charge carriers in this type of material The results of a study of the tempera- ture dependences of the Nernst coefficient for all the samples under study are pre- sented. An analysis of these dependencies is also given and values for the required parameters are obtained.
