Effects 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...

Subpicosecond Faraday Effect in Cd1–xMnxTe and Its Application in Magneto-Optical Sampling

208 LLE Review, Volume 99 Introduction Recent technological developments in electronics and optoelectronics have opened prospects for novel devices and digital circuits operating in the subpicosecond temporal regime.1–5 As the operating speed of modern electrical devices increases, the problem of how to properly characterize them becomes progressively more difficult. Independent measurements of...

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...

Relaxation of spin-glass magnetization in Cd1-xMnxTe diluted magnetic semiconductors.

Relaxation of thermal-remanent magnetization and isothermal remanent magnetization of spin glass in Cd& „Mn„Te diluted magnetic semiconductors have been studied at different conditions. Magnetization relaxation can be described by a power-law decay, M(t) =Mpt (f & to and to=2 s) with small values of a or a logarithmic decay M(t}=MD(1—a lnt) (t & to and to=2 s). Temperature and applied magnetic-...

Optical Properties of Cd1−xMnxTe Crystals near Fundamental Absorption Edge in Transverse Magnetic Fields

A simple and convenient model is proposed to elucidate the optical characteristics of Cd1−xMnxTe crystals using experimental data on light reflection in magnetic field. The model is based on the quasi-oscillator concept accounting both for the exciton and fundamental absorption edge contributions. The energy dependencies of refraction index and absorption coefficient are presented for Mn mole f...
