Zener Model Description of Ferromagnetism in Zinc-Blende Magnetic Semiconductors
TL;DR: Zener's model of ferromagnetism, originally proposed for transition metals in 1950, can explain T(C) of Ga(1-)(x)Mn(x)As and that of its II-VI counterpart Zn(1)-Mn (x)Te and is used to predict materials with T (C) exceeding room temperature, an important step toward semiconductor electronics that use both charge and spin.
Journal ArticleDOI
Probing the spin state of a single magnetic ion in an individual quantum dot.
TL;DR: In this paper, the fine structure of a confined exciton in the exchange field of a single Mn2+ ion (S=5/2) was analyzed in detail, and six emission lines were observed at zero magnetic field.
Journal ArticleDOI

TL;DR: In this article, the authors present a systematic study of the ferromagnetic transition induced by the holes in nitrogen doped epitaxial layers, with particular emphasis on the values of the Curie-Weiss temperature as a function of the carrier and spin concentrations.
Journal ArticleDOI

TL;DR: It is shown that both light beam and bias voltage generate an isothermal and reversible crossover between the paramagnetic and ferromagnetic phases, in the way that is predetermined by the structure design.
Journal ArticleDOI
Effect of thes,p−dexchange interaction on the excitons inZn1−xCoxOepilayers

TL;DR: In this article, the authors performed magneto-optical spectroscopy in the Faraday configuration, by applying a magnetic field up to 11T at temperatures down to 1.5K.
