Andreev-spectroscopy study of unconventional superconductivity in MgB₂:(La,Sr)MnO₃ nanocomposite

Krivoruchko, V.N.; D’yachenko, A.I.; Tarenkov, V.Yu. (Физика низких температур, 2014)

Unconventional high-temperature superconductivity in MgB₂:La₀:₆₅Sr₀:₃₅MnO₃ (MgB:LSMO) nanocomposite has been found recently [Phys. Rev. B 86, 10502 (2012)]. In this report, the symmetry of the nanocomposite superconducting ...
Electrically active magnetic excitations in antiferromagnets (Review Article)

Krivoruchko, V.N. (Физика низких температур, 2012)

The magnetic resonance operation by electric field is highly nontrivial but the most demanding function in the future spin-electronics. Recently observed in a variety of multiferroics materials named the collective ...
Enhancement of the Josephson current by magnetic field in superconducting tunnel structures with a paramagnetic spacer

Krivoruchko, V.N.; Koshina, E.A. (Физика низких температур, 2005)

The dc Josephson critical current of a (S/M)IS tunnel structure in a parallel magnetic field is investigated (here S is a superconductor, S/M is a proximity-coupled S and paramagnetic metal M bilayer, and I is an ...
Longitudinal magnetization dynamics in Heisenberg magnets: Spin Green functions approach

Krivoruchko, V.N. (Физика низких температур, 2018)

In spite of the fact that dynamical properties of magnets have been extensively studied over the past years, the longitudinal magnetization dynamics is still much less understood than transverse one even in the equilibrium ...
Longitudinal magnetization dynamics in Heisenberg magnets: Spin Green functions approach (Review Article)

Krivoruchko, V.N. (Физика низких температур, 2017)

Original article: Fiz. Nizk. Temp. 43, 1565-1574 ABSTRACT In spite of the fact that dynamical properties of magnets have been extensively studied over the past years, the longitudinal magnetization dynamics is still much ...
Peculiarities of electromagnetic waves absorption in polymer magnetic nanocomposites (La,Sr)MnO₃

The results of research of the nonresonant and magnetic resonance absorption of electromagnetic waves in polymer magnetic nanocomposites (La₀.₇Sr₀.₃Mn₀.₃) in 10-40 GHz and 60-78 GHz frequency bands are presented. The ...
Percolation transitions in d-wave superconductor–half-metallic ferromagnet nanocomposites

Krivoruchko, V.N.; Tarenkov, V.Y. (Физика низких температур, 2019)

Electrical transport properties of random binary networks composed of high-Tc superconductor Bi₂Sr₂Ca₂Cu₃O₆+x microparticles and half-metallic ferromagnet La₀.₆₇Sr0.₃₃MnO₃ (LSMO) nanoparticles have been investigated. ...
Point-contact Andreev-reflection spectroscopy of doped manganites: Charge carrier spin-polarization and proximity effects (Review Article)

Krivoruchko, V.N.; D’yachenko, A.I.; Tarenkov, V.Yu. (Физика низких температур, 2013)

Materials with spin-polarized charge carriers are the most demanded in the spin-electronics. Particularly requested are the so-called half-metals which have the maximum attainable value of carrier spin polarization. ...
Spin waves damping in nanometre-scale magnetic materials

Krivoruchko, V.N. (Физика низких температур, 2015)

Spin dynamics in magnetic nanostructured materials is a topic of great current interest. To describe spin motions in such magnetic systems, the phenomenological Landau–Lifshitz (LL), or the LL–Gilbert (LLG), equation is ...
Surface segregation and charge state of La₀.₇Sr₀.₃MnO₃

Danilenko, I.A.; Konstantinova, T.E.; Shatalova, G.E.; Krivoruchko, V.N.; Doroshev, V.D.; Stupak, V.A.; Volkova, G.K. (Functional Materials, 2006)

Nuclear magnetic resonance and secondary ion mass-spectroscopy have been used to study the surface charge and surface chemical compositions of La₀.₇Sr₀.₃MnO₃ nanoparticles of 12 and 50-100 nm size. It is found that the ...
