ABSTRACT
We report on the investigation of electron spin quantum beats at room temperature in GaAsN thin films by time-resolved Kerr rotation technique. The measurement of the quantum beats, which originate from the Larmor precession of electron spins in external transverse magnetic field, yields an accurate determination of the conduction electron g factor. We show that the g factor of GaAs1-xNx thin films is significantly changed by the introduction of a small nitrogen fraction.

    Zinc-blende structured MnAs epiaxial films with half metallic characteristics were grown on GaAs (100) substrates. The formation of the zinc-blende structured MnAs on GaAs was made possible via introduction of a strained yet epirelated InAs intermediate layer, the thickness of which was found...

    We study the Landé g-factor of conduction electrons in the L-valley of bulk GaAs and AlAs by using a three-band k·p model together with the tight-binding model. We find that the L-valley g-factor is highly anisotropic and can be characterized by two components g⊥ and g∥. g⊥...

    A double dot system with integrated charge readout is fabricated by combining direct oxidation of the GaAs surface of a Ga[Al]As-heterostructure with the local oxidation of a thin titanium film evaporated on top. The charge stability diagram is measured in direct transport through the dots as...

    A giant magnetocaloric effect was found in series of Mn1-xCoxAs films epitaxied on GaAs (001). The maximum magnetic entropy change caused by a magnetic field of 4 T is as large as 25 J/kg K around room temperature, which is about twice the value of pure MnAs film. The observed small thermal...

    Magnetotransport properties of epitaxially grown [formula] films on GaAs(001) substrates were investigated. The thickness of the films was adjusted to 250 nm, which is the characteristic thickness for showing a clear ladder-type magnetic domain structure. The broad magnetoresistance (MR)...

    We have studied the magnetic anisotropy of Ga1-xMnxAs thin films grown by low-temperature molecular beam epitaxy on GaAs (311)A substrates by means of ferromagnetic resonance spectroscopy. The angular dependence of the ferromagnetic resonance fields observed can be explained by two main...

    Ferromagnet/semiconductor heterostructure, such as Fe/GaAs, is always one of the key issues in spintronics due to its prerequisite for the realization of spin sensitive devices. In this letter, a lateral photoelectric effect (LPE) was observed in Fe/GaAs. Our results show that the sensitivity...

    We report high resolution laser absorption spectroscopy of a single InGaAs/GaAs self-assembled quantum dot embedded in a field-effect structure. We show experimentally that the interband optical absorption to the lower Zeeman branch of the singly charged exciton is strongly inhibited due to spin...
