Enhancement of Electron Spin Polarization in Semiconductors
An extension of the original Overhauser effect to a more general nonequi-librium state was proposed by G. Feher, and demonstrated by Clark and Feher some forty years ago. It is suggested here that it might be possible to produce excess electron spin polarization by allowing the role of the nuclei to be played by other magnetic entities, such as paramagnetic impurities or adjacent magnetically o...
متن کاملCorrelation energy and spin polarization in the 2D electron gas.
The ground-state energy of the two-dimensional uniform electron gas has been calculated with a fixed-node diffusion Monte Carlo method, including backflow correlations, for a wide range of electron densities as a function of spin polarization. We give a simple analytic representation of the correlation energy which fits our simulation data and includes several known high- and low-density limits...
متن کاملElectron Spin Polarization : a New Tool in Photoemission and Magnetism
A review of the technique of measuring the spin polarization P of photoemitted electrons and of results of measurements from a variety of magnetic materials is presented. Photoelectric magnetization curves are obtained by measuring P as a function of applied magnetic field, while measuring P as a function of photon energy gives a spectrum of spin polarization which locates magnetic states in an...
متن کاملCell-Length-Dependent Microtubule Accumulation during Polarization
BACKGROUND Breaking cell symmetry, known as polarization, requires dynamic reorganization of microtubules (MTs) and is essential to many cellular processes, including axon formation in neurons. A critical step in polarization is believed to be the "selective stabilization" of MTs, which hypothesizes a spatial and/or temporal shift toward net MT assembly in a preferred direction of growth. RES...
متن کاملMAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...
