Spin-dependent scattering and magnetic proximity effect in Ni-doped Co/Cu multilayers as a probe of atomic magnetism

Autor: Tykhonenko-Polishchuk, Yu O, Polishchuk, D M, Polek, T I, Yaremkevych, D D, Kravets, A F, Tovstolytkin, A I, Timoshevskii, A N, Korenivski, V

We investigate the spin transport and ferromagnetic resonance properties of giant magnetoresistive (GMR) Co/Cu-Ni multilayers with variable levels of Ni doping in the Cu spacer. We present an experimental evidence for a magnetic-to-diamagnetic transi

Temperature-controlled interlayer exchange coupling in strong/weak ferromagnetic multilayers: a thermo-magnetic Curie-switch

Autor: Kravets, A., Timoshevskii, A. N., Yanchitsky, B. Z., Bergmann, M., Buhler, J., Andersson, S., Korenivski, V.

Publikováno v: Phys. Rev. B 86 (2012) 214413

We investigate a novel type of interlayer exchange coupling based on driving a strong/weak/strong ferromagnetic tri-layer through the Curie point of the weakly ferromagnetic spacer, with the exchange coupling between the strongly ferromagnetic outer

Ab-initio modeling of the short range order in Fe-N and Fe-C austenitic alloys

Autor: Timoshevskii, A. N., Yablonovskii, S. O.

In the present paper, we have studied atomic structure of nitrogenous austenite. High precision ab-initio calculation was utilized for the calculation of the pair potentials of interatomic interactions N-N in FCC Fe lattice. These potentials were use

First-principles calculations atomic structure and elastic properties of Ti-Nb alloys

Autor: Timoshevskii, A. N., Yablonovskii, S. O., Ivasishin, O. M.

Elastic properties of Ti based \beta-alloy were studied by the method of the model structure first principle calculations. Concentrational dependence of Young modulus for the binary \beta-alloy Ti-Nb was discovered. It is shown that peculiarities vis

On chemical bonding of Helium with hcp-Beryllium

Autor: Bakai, A. S., Timoshevskii, A. N., Yanchitsky, B. Z.

Chemical inertness is the key property of helium determining its solubility, distribution and accumulation kinetics in metals. Against all expectations, our ab initio calculations show a substantial chemical bonding between He and Be atoms in the hcp
