  • Spin and current variations in Josephson junctions 
    Shnirman, A.; Nussinov, Z.; Jian-Xin Zhu; Balatsky, A.V.; Makhlin, Yu. (2004)
    We study the dynamics of a single spin embedded in the tunneling barrier between two superconductors. As a consequence of pair correlations in the superconducting state, the spin displays rich and unusual dynamics. To ...
  • Spin ballistic transport and quantum intreference in mesoscopic loop structures 
    Tralle, I.; Pasko, W. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    In the paper, a simple theory of quantum inteference in a loop structure caused by spin coherent transport and the Larmor precession of the electron spin is presented. A “spin ballistic” regime is supposed to occur, when ...
  • Spin Chains with Non-Diagonal Boundaries and Trigonometric SOS Model with Reflecting End 
    Filali, G.; Kitanine, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    In this paper we consider two a priori very different problems: construction of the eigenstates of the spin chains with non parallel boundary magnetic fields and computation of the partition function for the trigonometric ...
  • Spin, confinement, localization and supersymmetry 
    Cirilo-Lombardo, Diego Julio (Вопросы атомной науки и техники, 2012)
    New mechanism of localization of fields in a particular sector of a special supermanifold is proposed and described, based on previous works of the authors. Different aspects of this new mechanism are discussed as an ...
  • Spin-dependent binding of dioxygen to heme and charge-transfer mechanism of spin-orbit coupling enhancement 
    Minaev, B.F.; Minaeva, V.A. (2008)
    Spin-orbit coupling (SOC) between the starting triplet ³A''(2) state from the entrance channel of the heme-O2 binding reaction and the final singlet ¹A'(1) open-shell state, which are dominated by the Fe^3+-O2-radical-pair ...

    Tretyak, O.V.; Kozonushchenko, O.I.; Krivokhizha, K.V.; Revenko, A.S. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2010)
    We have used electrically detected spin-dependent paramagnetic resonance to investigate the non-equilibrium conductivity in a silicon diode. In order to create paramagnetic centers, we used diode with a polished surface ...
  • Spin-dependent transport in compacted powders of chromic dioxide CrO₂ with anisotropy of nanoparticle shapes 
    Dalakova, N.V. (Functional Materials, 2015)
    Resistive and magnetoresistive properties of compacted powders consisting of nanosized particles of chromic dioxide CrO₂ with dielectric β-CrOOH shells are studied. Anisotropy of tunnel magnetoresistance which is responsible ...
  • Spin-dependent transport in magnetic sandwiches in the effective-mass approximation 
    Los’, V.F.; Saltanov, V.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2006)
    A theory describing a spin-dependent transport of electrons through a thin metallic (or insulator) nonmagnetic layer sandwiched between two ferromagnets is developed in the ballistic regime and current-perpendicular-to-plane ...
  • Spin dephasing in pseudomagnetic fields: susceptibility and geometry 
    Tokatly, E.Ya.; Sherman, I.V. (Физика низких температур, 2016)
    We present a theory of spin dynamics caused by spin-orbit coupling for two-dimensional gases of cold atoms and other quasiparticles with pseudospin 1/2 moving in orbital gauge fields. Our approach is based on the gauge ...

    Sherman, A.; Schreiber, M. (Физика низких температур, 2006)
    Results obtained with the use of the t–J model of Cu–O planes and Mori’s projection operator formalism are compared with data of neutron scattering experiments in lanthanum and yttrium cuprates. This comparison allows ...
  • Spin dynamics of ³He-B with dissipation for the general spin-orbital configurations 
    Kharadze, G.; Suramlishvili, N. (Физика низких температур, 1999)
    The spatially homogeneous spin dynamics of the superfluid ³He-B with dissipation is considered for the general spin-orbital configurations. It is demonstrated that the possibility of new coherent spin- precessing modes ...
  • Spin dynamics of S = 1/2 Heisenberg chains with a staggered transverse field: electron spin resonance studies (Review Article) 
    Zvyagin, S.A. (Физика низких температур, 2012)

    Omelyan, I.P.; Mryglod, I.M.; Folk, R. (Condensed Matter Physics, 2000)
    A novel approach is developed for computer simulation studies of dynamical properties of spin liquids. It is based on the Liouville operator formalism of Hamiltonian dynamics in conjunction with Suzuki-Trotter-like ...
