The magnetization induced in a superconductor due to the reverse proximity effect is studied in hybrid structures containing a superconductor and a ferromagnetic insulator. The study was carried out within the method of semiclassical Green’s functions, in which the Usadel equations are solved numerically with boundary conditions suitable for strongly spin-polarized ferromagnetic materials. The conversion ...

This paper presents a theoretical study of the dynamics of the induced magnetization and spin current
arising in a layer of an dirty superconductor due to the proximity to a ferromagnetic dielectric with a
uniform periodically precessing magnetization. The dynamics of the observed physical quantities is described
within the semi-classical Usadel–Floquet formalism, which makes it possible to study ...

The magnetization in a superconductor induced due to the inverse proximity effect is
investigated in hybrid bilayers containing a superconductor and a ferromagnetic
insulator or a strongly spin-polarized ferromagnetic metal. The study is performed
within a quasiclassical Green function framework, wherein Usadel equations are solved
with boundary conditions appropriate for strongly spin-polarized ferromagnetic
materials. A comparison with recent experimental data ...

We investigate the behavior of the critical temperature T_c in superconductor/ferromagnet/superconductor (S/F/S) trilayers in the dirty limit as a function of the ferromagnetic layer thickness d_f and the S/F interface transparency. We perform T_c calculations using the general self-consistent multimode approach based on the Usadel equations in Matsubara Green’s functions technique, and compare the results ...

We report the observation of a current-phase relation dominated by the second Josephson harmonic in superconductor-ferromagnet-superconductor junctions. The exotic current-phase relation is realized in the vicinity of a temperature-controlled 0-to-π junction transition, at which the first Josephson harmonic vanishes. Direct current-phase relation measurements, as well as Josephson interferometry, non-vanishing supercurrent and half-integer Shapiro steps at ...

We study the peculiarities in current-phase relations (CPR) of the SIsFS junction in the region of 0 to p
transition. These CPR consist of two independent branches corresponding to 0− and p− states of the contact.
We have found that depending on the transparency of the SIs tunnel barrier the decrease of the s-layer thickness
leads to transformation ...

We propose a superconducting spin-triplet valve of a new type. This spin valve consists of a bilayer
that involves a superconductor and an itinerant magnetic material, with the magnet showing an
intrinsic non-collinear magnetic order characterized by a wave vector Q that may be aligned in a
few equivalent preferred directions under control of a weak external magnetic ...

Сверхпроводимость и магнетизм в однородной системе способствуют двум противоположным видам спинового упорядочения валентных электронов. Однако, в структурах где ферромагнетик (F) соседствует со сверхпроводником (S), взаимовлияние этих двух типов упорядочения приводит к целому ряду интересных эффектов, один из которых обратный эффект близости. Он заключается в том, что вблизи SF границы равновесное спиновое распределение электронов проводимости изменяется ...
