Abstract: Tunnel junction between a metal partially gapped by charge density waves metal (CDWM) and a ferromagnet (FM) in an external magnetic field is considered. Only the Zeeman paramagnetic effect is taken into account. It is shown that the peaks in the dependence of differential conductance vs. voltage, induced by the CDW gap, split, each peak having a predominant spin polarization. This effect makes it possible to electrically measure the polarization of current carriers in FMs.
