ABSTRACT
Electron spin dynamics in n-type c-oriented wurtzite GaN epilayers is studied by time-resolved Kerr-rotation measurements at T=80 K. The electron spin lifetime shows a sudden increase if an external magnetic field is applied in the sample plane. This enhancement is explained by anisotropic Dyakonov–Perel spin relaxation in bulk GaN as a direct consequence of the anisotropy of spin-orbit coupling in semiconductors with wurtzite structure.

    High-field electron paramagnetic resonance (EPR) is used to investigate two magnetically concentrated II1-xMnxVI alloys, Cd1-xMnxSe and Cd1-xMnxSe, for x>0.15. Earlier EPR studies carried out between 9.0 and 35 GHz had shown that the EPR linewidths in II1-xMnxVI alloys are determined by...

    The microwave magnetoresistivity of lightly doped (nondegenerate) p-Ge has been studied by the electron spin resonance method. This technique can be employed to record the derivative of the microwave absorption with respect to the magnetic field on the assumption that changes in this absorption...

    The EPR spectra of Ce impurity ions in LiYF, LiLuF, and LiTmF double-fluoride single crystals have been investigated at a frequency of ∼9.3 GHz in the temperature range 5-25 K. The effective g factors of the ground Kramers doublet of the cerium ions in three crystals are close to each other...

    We performed high-field magnetization measurements, M( H), on the Ni5(TeO3)4Br2 by using a pulse magnet. The Ni2+ ions ( S = 1) of this compound form a two dimensional distorted spin frustrated system (distorted kagome lattice), and undergo a Neel transition at T N~29 K, due to the anisotropy....

    Electron g-factors in self-assembled InAs/GaAs quantum dots are studied theoretically by means of a tight-binding method. The anisotropy in the electron g-factor, induced by the band-mixing effect, is found to be much more sensitive to the chemical composition of the dot than the aspect ratio of...

    The Eu2+ (4f7, S=7/2) g value in Ca1-xEuxB6 (0.15<=x<=1.00) was measured by means of electron spin resonance at two frequencies (fields), 9.4 (≈3.4 kOe) and 34.4 GHz (≈12.1 kOe). The g value was found to be anisotropic and magnetic-field dependent. The amplitude of the anisotropy...

    Capillary force mechanisms have the advantages of providing the motive force to move groups of particles to locations of interest while holding them in place, offering delicateness, and obviating the use external energy sources. We report a capillary force method that permits particles to remain...

    We study hot-electron capture on resonant N-impurities in the dilute nitride Ga(AsN) alloy under high magnetic fields up to 23 T. We show that when the ratio of electric and magnetic fields reaches a critical value, the trajectory of conduction electrons becomes fully localized in real space;...

    The anomalous magnetoresistance (MR) of the interference origin was first observed in the weakly doped nongenerated n-Ge:Sb and p-Ge:Ga. Early proposed for the MR detection, the electron spin resonance technique was used for this investigation. It was found that the anomalous MR was observed in...
