Collective character of spin excitations in a system of Mn spins coupled to a two-dimensional electron gas
F. J. Teran, M. Potemski, D. K. Maude +7
We have studied the low energy spin excitations in n-type CdMnTe based dilute magnetic semiconductor quantum wells. For magnetic fields for which the energies for the excitation of…

Glass Transition in a Two-Dimensional Electron System in Silicon in a Parallel Magnetic Field
J. Jaroszynski, Dragana Popovic, T. M. Klapwijk
Studies of low-frequency resistance noise show that the glassy freezing of the two-dimensional electron system (2DES) in Si in the vicinity of the metal-insulator transition (MIT)…
