Anomalous Magnetoresistance in Dirty Magnetic Quantum Wells
... A giant Zeeman splitting in (Cd,Mn)Te quantum wells brings Landau levels into coincidence and gives rise to the formation of the Quantum Hall Ferromagnets (QHFM) at selected fields B c [1]. Here we report on new findings at the low-B limit. Since spin- polarization increases as B decreases magnetore ...
