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…
Stochastic resonance in a quasi-two-dimensional superlattice. II
G. M. Shmelev, E. M. Epshtein, A. S. Matveev
A fluctuation theory is presented for the nonequilibrium second order phase transition in a quasi-two-dimensional electron gas. A transverse (with respect to the current through th…
Hysteresis of static polarizability of a ballistic ring in presence of intense high-frequency field
E. M. Epshtein, G. M. Shmelev
A ballistic ring in presence of collinear dc and high-frequency electric fields is considered. A possibility is demonstrated of the system switching between two states by changing…
Resonant excitation of the domain wall oscillations by a parallel current under spin injection
R. J. Elliott, E. M. Epshtein, Yu. V. Gulyaev +1
A possibility is discussed of observing spin injection effect on the ferromagnet domain structure by means of resonant excitation of the domain wall oscillations by a spin-polarize…
Nonuniform switching ferromagnetic layers by spin polarized current
R. J. Elliott, E. M. Epshtein, Yu. V. Gulyaev +1
The magnetic reversal by spin-polarized current of a magnetic junction consisting of two ferromagnetic layers and a nonmagnetic spacer in between is considered. Initially, the free…
