A longitudinal magneto-optical Kerr effect and magnetization-induced second-harmonic generation (MSHG) of light (at 2v) have been measured in a SiO2/Fe96Si4/Dy30Fe58Co12/glass exchange-coupled magnetic bilayer system with competitive anisotropies. Theoretical MSHG predictions in this structure that give rise to an effect proportional to magnetization components and that are allowed by an electr...

We report on the observation of magnetic quantum ratchet effect in metal-oxide semiconductor field-effect-transistors on silicon surface (Si-MOSFETs). We show that the excitation of an unbiased transistor by ac electric field of terahertz radiation at normal incidence leads to a direct electric current between the source and drain contacts if the transistor is subjected to an in-plane magnetic ...

We calculate the local density of states for a relativistic massless particle in the presence of crossed electric and magnetic fields. The Landau levels are broadened and aquire a modulation due to the electric field. We give detailed predictions for the shape of Landau levels in the relativistic case based on analytical expressions.

In this article, the effect of direct current electric field on the phenol biodegradation by laccase was studied. The results showed that the DC electric field could enhance the biodegradation activity of laccase. Specifically, the rate of phenol biodegradation when catalyzed by laccase was significantly higher in the presence of the DC electric field than in its absence. In the presence of the...

We derive the extension of the Hubbard model to include Rashba spin-orbit coupling that correctly describes Aharonov-Bohm and Aharonov-Casher phases in a ring under applied magnetic and electric fields. When the ring is connected to conducting leads, we develop a formalism that is able to describe both, Kondo and interference effects. We find that in the Kondo regime, the spin-orbit coupling re...

Three terminal superconducting electric-field effect devices, consisting of a bufferlayer of PrBa2Cu307 -x, an ultrathin layer of YBa2CuaOT_x and a SrTiO3 gate isolation layer were fabricated and successfully operated. Transmission electron microscopy and laser scanning microscopy showed that all layers are highly epitaxial and uniform over the device area. This is essentially important in the ...

Performing state-of-the-art ab initio calculations we study the effect of the electric field on magnetic properties of Co and Co-Pt chains on Pt(111). Our studies give clear evidence that an externally applied electric field could permit one to tailor magnetic anisotropy in chains. It is demonstrated that the physics behind this effect is related to the spin-dependent screening of an external e...

We reported the non-volatile electric field-mediated magnetic properties in the half-metallic Heusler alloy Co2FeAl/Pb(Mg1/3Nb2/3)O3-PbTiO3 heterostructure at room temperature. The remanent magnetization with different applied electric field along [100] and [01-1] directions was achieved, which showed the non-volatile remanent magnetization driven by an electric field. The two giant reversible ...

We investigate the effect of internal electric field in InGaN well layer of InGaN/GaN multiple quantum well light-emitting diodes (LEDs) on efficiency droop behavior. The simulation results show that the internal electric field in InGaN well layers of Ga-polar LEDs is same as the direction of external electric field by forward bias voltage, resulting in a strong efficiency droop. However, N-pol...

We consider in this paper a plasma subject to a strong deterministic magnetic field and we investigate the effect on this plasma of a stochastic electric field. We show that the limit behavior, which corresponds to the transfer of energy from the electric wave to the particles (Landau phenomena), is described by a Spherical Harmonics Expansion (SHE) model.
