題目：「Spin-dependent tunnel currents in junctions between ferromagnets andnormal metals (superconductors) with charge-density waves」

要旨：
A new experimental scheme to study a spin polarization P 
of ferromagnets is proposed. Specifically, normal or 
superconducting metals partially gapped by charge density 
waves (CDWs) are suggested as a probe of P while measuring
dynamic conductivity G(V) of tunnel junctions between CDW 
metals and ferromagnets in external magnetic fields. 
Calculated G(V) are substantially differentfrom those in 
the case of the superconductor-insulator-ferromagnet 
structures, being well-known probes of P.Theexisting 
variety of CDW substances with critical temperatures 
and energy gaps substantially exceeding their superconducting 
counterparts constitute an advantage of the proposed set-up.
