We investigate the superconducting phase transition in a superconductor (S)/ferromagnet (F) bilayer with Rashba spin-orbit interaction at the S/F interface. This spin-orbit coupling produces spontaneous supercurrents flowing inside the atomic-thickne

In P-doped pnictide, ${\mathrm{EuFe}}_{2}{({\mathrm{As}}_{1\ensuremath{-}x}{\mathrm{P}}_{x})}_{2}$ superconductivity coexists with a ferromagnetism of $\mathrm{Eu}\text{\ensuremath{-}}4f$ spins. Above $x\ensuremath{\simeq}0.26$, superconductivity van

Crossover between standard and inverse spin-valve effect in atomically thin superconductor/half-metal structures

Autor: Zh. Devizorova, S. Mironov

Publikováno v: Physical Review B. 100

Spin-singlet Cooper pairs consisting of two electrons with opposite spins cannot directly penetrate from a superconductor to a half-metal (fully spin polarized ferromagnets) which blocks the superconducting proximity effect between these materials. I

The spin-triplet correlations in superconducting spin valve structures arising in the presence of noncollinear textures of magnetic moment are shown to enhance strongly the electromagnetic proximity effect, i. e. the long-range leakage of the magneti

Fermi arcs formation in Weyl semimetals: The key role of intervalley interaction

Autor: Zh. Devizorova, V. A. Volkov

Publikováno v: Physical Review B. 95

We propose an analytical model describing Fermi arc surface states observed in the recent investigations of Weyl semimetals. The effective two-valley Hamiltonian is supplemented by the boundary conditions taking into account both the intravalley and
