Paramagnetic spin splitting of the conductances for tunnel junctions between partially gapped metals with charge density waves and normal metals or ferromagnets
Abstract:We consider tunnelling between a metal partially gapped by charge density waves (CDWM) and an
ordinary metal (M) or a ferromagnet (FM) separated by an insulator (I) in an external magnetic field
H. Zeeman paramagnetic splitting is assumed to dominate in the
CDWM over orbital magnetic effects. The quasiparticle tunnel current
J and relevant
differential conductance G
are calculated as functions of the bias voltage
V. The
peaks of G(V), originating from the electron density of states singularities near the char… Show more
