Monte Carlo simulations of ferromagnetism in p-Cd1-xMnxTe quantum wells.
Monte Carlo simulations, in which the Schrödinger equation is solved at each Monte Carlo sweep, are employed to assess the influence of magnetization fluctuations, short-range antiferromagnetic interactions, disorder, magnetic polaron formation, and spin-Peierls instability on the carrier-mediated Ising ferromagnetism in two-dimensional electronic systems. The determined critical temperature an...
متن کاملNuclear spin dynamics in parabolic quantum wells
We present a detailed analytical and numerical analysis of the nuclear spin dynamics in parabolic quantum wells. The shallow potential of parabolic quantum wells permits substantial modification of the electronic wave function in small electric fields. The nuclear spin relaxation via the hyperfine interaction depends on the electronic local density of states, therefore the local nuclear relaxat...
متن کاملCollective excitations in asymmetric parabolic quantum wells
We study within the linear response theory the far-infrared optical absorption spectrum and the collective excitations of an asymmetric, wide parabolic AlxGa1−xAs quantum well, consisting of two half-parabolas of different curvatures, in the presence of an in-plane magnetic field. We employ a self-consistent-field approach in the local-density approximation using parameter values of a recent ex...
متن کاملComparison of Zn1−xMnxTe/ZnTe multiple-quantum wells and quantum dots by below-bandgap photomodulated reflectivity
Large-area high density patterns of quantum dots with a diameter of 200 nm have been prepared from a series of four Zn0.93Mn0.07Te/ZnTe multiple quantum well structures of different well width (40 Å, 60 Å, 80 Å and 100 Å) by electron beam lithography followed by Ar-ion beam etching. Below-bandgap photomodulated reflectivity spectra of the quantum dot samples and the parent heterostructures were...
متن کاملEffects of Spin Polarization on Electron Transport in Modulation Doped Cd1−xMnxTe/Cd1−yMgyTe:I Heterostructures
We examine and identify magnetoresistance mechanisms in 2D system containing a sizable concentration of magnetic ions. We argue that some of these mechanisms can serve as a tool to measure spin polarization. Lack of spin degeneracy and enhanced localization make it possible to detect an additional QHE plateau associated with extended states floating-up in vanishing magnetic field. In diluted ma...
