Double stochastic resonance in conductors with narrow conduction band
E. M. Epshtein, T. A. Gorshenina, G. M. Shmelev
Results are presented of studying the stochastic resonance (SR) in conductors with bcc lattice and narrow conduction band. In such materials, SR has a feature, namely, the weak-sig…
Current induced spin injection and surface torque in ferromagnetic metallic junctions
R. J. Elliott, E. M. Epshtein, Yu. V. Gulyaev +1
Joint influence of two effects, namely, nonequilibrium spin injection by current, and current induced surface torque, on spin-valve type ferromagnetic metallic junctions is conside…
Vibrational resonance in narrow-band conductors
G. M. Shmelev, E. M. Epshtein, A. S. Matveev
The response is studied of a narrow-band conductor with bcc lattice to a low-frequency signal under presence of a high-frequency signal. In a high enough dc electric field Ex, the…
On the second harmonic generation in superlattices
G. M. Shmelev, E. N. Valgutskova, E. M. Epshtein
In present work, we investigate the second harmonic generation in a superlattice under presence of the carrier density gradient. We show that the second harmonic intensity can be c…
Quasi-one-dimensional ballistic ring in the field of circularly polarized electromagnetic wave
E. M. Epshtein, E. G. Fedorov, G. M. Shmelev
Dynamics is studied of an electron in a quasi-one-dimensional ballistic ring under circularly polarized electromagnetic field propagating along the normal to the ring plane. The av…
Quasi-one-dimensional ballistic ring in crossed high-frequency electric fields
E. M. Epshtein, E. G. Fedorov, G. M. Shmelev
We study electron dynamics in a quasi-one-dimensional ballistic ring driven by two crossed high-frequency electric fields parallel to the ring plane. The averaged dipole moment and…
