    Abstract

    The anomalous conducting phase that has been shown to exist in zero magnetic field in dilute two-dimensional electron systems in silicon is driven into a strongly insulating state by a magnetic field of about 2 T applied at any angle to the 2D plane. Once the conducting phase is quenched, the behavior of this system in a magnetic field is similar to that of disordered GaAs/A1GaAs heterostructures. Our results demonstrate that the suppression of the conducting phase is related only to the electrons' spin.
