fieldE.bE × Bgenerated a finite electron currentJsince the ions are not magnetized at this scale. In the distorted field lines, electrons tend to propagate along the magnetic field. This enhances the field distortion and current.cBy adding an ambient medium, an external pressure is ...
Magnetic exchange field from an EuS substrate breaks the valley degeneracy for monolayer WSe2, leading to enhanced valley splitting. Exploiting the valley degree of freedom to store and manipulate information provides a novel paradigm for future electron
These assumptions are not valid when the magnetic field is strong. It was shown in Sect.4.6.2 that the energy-wave-vector dispersion relation is altered in magnetic fields. The component of the electron energy corresponding to the electron wave vector transverse to the magnetic field is ...

We discuss the significance of this quantization for the Hall effect in an electron gas which is only able to move in two dimensions, perpendicular to the direction of the magnetic field鈥doi:10.1142/9789814439367_0006Henrik SmithUniversity of copenhagen, Denmark...

Material atoms that have unpaired electrons that are oriented randomly in the absence of a magnetic field show paramagnetic behavior. When a magnetic field is applied to such a material, electron spins tend to align with the magnetic field and cause a positive magnetization. The degree of ...
1.2.1 Electromagnetic Field Variables The basic idea underlying electromagnetic theory is that space is permeated with electric and magnetic fields whose spatial and temporal variations are coupled to one another and are related to source densities (ie, distributions of charges and currents). The elec...
We observe an inversion of the low-temperature dependence for the conductivity of doped GaAs by application of a magnetic field. This inversion happens when ωcτtr1, as predicted by Houghton et al. [Phys. Rev. B 25, 2196 (1982)] for the correction to conductivity due to screened Coulomb...
The electron flow vectors in the reconnection plane are derived from the electron current profile, which is obtained from the magnetic field profile measured by fine scale magnetic probes. Specifically, we use the equations J = ∇×B /μ0 and Ue = −J/nee + Ui to compute...
