Ferromagnetic correlations in quasi-one-dimensional conducting channels
arXiv:cond-mat/9911175 · doi:10.1103/PhysRevB.61.16730
Abstract
We propose a model which explains the experimental observation of spontaneous spin polarization of conducting electrons in quasi- one-dimensional GaAs/AlGaAs channels. We show that a ferromagnetic order is a generic property of a quasi-one-dimensional conducting channel embedded in a Wigner crystal. We also discuss gate voltage, magnetic field and temperature dependences of the channel's conductance.
