چکیده
Theoretical description of the ferromagnetic π-junctions near the critical temperature Abstract The theory of ferromagnetic π-junction near the critical temperature is presented. It is demonstrated that in the dirty limit the modified Usadel equation adequately describes the proximity effect in ferromagnets. To provide the description of an experimentally relevant situation, oscillations of the Josephson critical current are calculated as a function of ferromagnetic layer thickness for different transparencies of the superconductor-ferromagnet interfaces.

We study numerically the electronic heat capacity, spin and charge current in a diffusive Superconductor-Ferromagnetic-Superconductor systems، with singlet superconducting leads and non-uniform ferromagnetic layer. Specially, we focus on ferromagnetic layer with domain wall and conical structures incorporation the spin-active interfaces. We investigate, how the 0-π transition is influenced by n...
متن کاملProximity Effects in Superconductor-ferromagnet Heterostructures
The very special characteristic of the proximity effect in superconductor-ferromagnet systems is the damped oscillatory behavior of the Cooper pair wave function in a ferromagnet. In some sense, this is analogous to the inhomogeneous superconductivity, predicted long time ago by Larkin and Ovchinnikov (1964), and Fulde and Ferrell (1964), and constantly searched since that. After the qualitativ...
متن کاملFerromagnetic 0–π Josephson junctions
We present a study on low-Tc superconductorinsulator-ferromagnet-superconductor (SIFS) Josephson junctions. SIFS junctions have gained considerable interest in recent years because they show a number of interesting properties for future classical and quantum computing devices. We optimized the fabrication process of these junctions to achieve a homogeneous current transport, ending up with high...
متن کاملPeculiar properties of the Josephson junction at the transition from 0 to π state
It is demonstrated that in the diffusive superconductor-ferromagnetsuperconductor (S/F/S) junctions the current-phase relation is practically sinusoidal everywhere except in a narrow region near the 0−π transition. In this region the second harmonic dominates the scenario of the 0 − π transition. We predict a first order transition for the S/F/S junctions with a homogeneous F barrier. However, ...
متن کاملRealization of φ Josephson Junctions with a Ferromagnetic Interlayer
In this thesis, φ Josephson junctions based on 0-π junctions with a ferromagnetic interlayer are studied. Josephson junctions (JJs) with a ferromagnetic interlayer can have a phase drop of 0 or π in the ground state, depending on the thickness of the ferromagnet (0 JJs or π JJs). Also, 0-π JJs can be realized, where one segment of the junction (if taken separately) is in the 0 state, while the ...
