Modeling of the superconducting triplet spin valve with several superconductor layers

Using the matrix method for solving the linearized Usadel equations, the critical temperature and the distribution of singlet pairing components of the superconductor/ferromagnet/superconductor/ferromagnet structure with nonideal boundaries are obtained. A transition from the π- to the 0-phase state between layers of superconductors was obtained with a change in the angle between the magnetizations of ferromagnetic layers in such a structure.
