Abstract
We study the critical temperature Tc of FSF trilayers (F is a
ferromagnet, S is a singlet superconductor), where the triplet
superconducting component is generated at noncollinear magnetizations of the
F layers. An exact numerical method is employed to calculate Tc as a
function of the trilayer parameters, in particular, mutual orientation of
magnetizations. Analytically, we consider limiting cases. Our results
determine conditions which are necessary for existence of recently
investigated odd triplet superconductivity in SF multilayers.
