Magnetic hard gap due to bound magnetic polarons in the localized regime
We investigate the low temperature electron transport properties of manganese doped lead sulfide films. The system shows variable range hopping at low temperatures that crosses over into an activation regime at even lower temperatures. This crossover is destroyed by an applied magnetic field which suggests a magnetic origin of the hard gap, associated with bound magnetic polarons. Even though t...
متن کاملMagnetic fluctuation observation in donor-bound magnetic polarons
2014 The energy distribution of donor-bound magnetic polarons is studied in CdMnS and CdMnSe alloys, using the spin-flip Raman scattering technique. The influence of magnetic fluctuations on the lineshapes is proved Evidence of the superparamagnetism of giant moments associated to magnetic polarons is also reported J. Physique 45 (1984) 1071-1077 JUIN 1984, Classification Physics Abstracts 78.2...
متن کاملEvaluating the Changes in Alpha-1 Band Due to Exposure to Magnetic Field
Introduction Increase in alpha band is observed when blood perfusion in frontal area of head decreases. The present study evaluated some changes in the alpha band particularly, alpha-1 of frontal and central areas of the head, when several areas were exposed simultaneously to magnetic field. Materials and Methods Five points of head (F3, F4, Cz, T3, and T4) of twenty healthy male participants w...
متن کاملTEM INVESTIGATION OF RAPIDLY SOLIDIFIED NDFEB HARD MAGNETIC MATERIAL
The surface condition and microstructure of near stoichiometric (Fe823Ndll.8B5.9) Nd-Fe-B alloy ribbons and the effect of melt spinning parameters were investigated using optical, scanning and transmission electron microscopes (SEM, TEM). The formation of gas pockets on the roll surface of the ribbons during melt spinning can prevent heat transform and result in local coarse grains. The local t...
