Phase Diagram and Thermodynamic Properties of Layered Ferromagnet-Superconductor Nanostructures

ORAL

Abstract

We present results obtained by exact, fully self-consistent numerical solution of the microscopic Bogoliubov-DeGennes equations for Superconductor/Ferromagnet (S/F) nanostructures in the clean limit. We discuss the thermodynamics of SFS trilayers, including the complete phase diagram over experimentally relevant parameter range. Both the first order $0$ to $\pi$ transition and the second order transition to the normal state at $T_c$ are included. We find excellent agreement between theoretical and experimental results for $T_c$. Other relevant quantities such as DOS, magnetization, and conductivity will also be discussed.
