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
Optically detected carrier confinement to one and zero dimension in GaAs quantum well wires and boxes
TL;DR: In this article, a carrier confinement to one and zero degrees of freedom has been achieved in artificial quantum well wires and boxes fabricated in the GaAs•GaAlAs system, which is attributed to transitions arising from ground and excited levels of electrons within these low dimensional structures.
Journal ArticleDOI
High-Curie-temperature ferromagnetism in self-organized Ge1-xMnx nanocolumns.

TL;DR: In this paper, a high-TC (>400 K) ferromagnetic phase of (Ge,Mn) epitaxial layer is reported, and the average diameter of these nanocolumns is 3 nm and their spacing is 10nm.
Journal ArticleDOI
Observation of a Ferromagnetic Transition Induced by Two-Dimensional Hole Gas in Modulation-Doped CdMnTe Quantum Wells
A. Haury,A. Wasiela,Alexandre Arnoult,Joel Cibert,Serge Tatarenko,Tomasz Dietl,Tomasz Dietl,Y. Merle d'Aubigné +7 more
TL;DR: In this paper, the presence of a ferromagnetic transition in single, modulation-doped, 8 nm quantum well was demonstrated by photoluminescence magnetospectroscopy.
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.
