Acesso em:.https://bdm.ufpa.br/jspui/handle/prefix/7012This final paper aims to present general aspects of the phenomenon of superconduc tivity. The historical facts that led H. K. Onnes, in 1911, saw an abrupt drop in the resistance of the mercury; thus opening a new branch in physics at low temperature. From this, discuss quantitative and qualitative form as phenomenological theories, Lon don equation and Landau-Ginzburg approach, and the description complete of supercon ductivity. Once this is done, the discussion on superconducting cuprates begins, which was discovered by J. G. Bednorz and K. A. Müller in 1986. Therefore, in this work, it will be considered a crystalline structure, specifically, the copper-oxygen planes, because they play a key role in the phenomenon of superconductivity. Furthermore, we discuss the doping mechanism and we present the microscopic model to describe the electronic dynamics, comparing our theoretical result with data experimental.Acesso AbertoSupercondutividadeCupratos supercondutoresModelo spin-férmion HubbardCNPQ::CIENCIAS EXATAS E DA TERRA::FISICATrabalho de Curso - Graduação - Monografia
