| Popis: | It is well known that the anharmonic interaction between quasiparticles controls both the dynamic and transport properties of solids. Recently it was shown that paramagnetic impurities induce indirect magnon‐magnon and magnon‐phonon interactions in dielectric magnetic materials.1 These anharmonic couplings of an ‘‘impure’’ origin explain the unusual (peaklike) temperature dependence of magnon and phonon relaxation rates in magnetic dielectrics. Later, this idea was applied to disordered ferromagnetic metals and it was shown that in metals magnetic impurities induce effective coherent magnon‐electron coupling2 which changes radically the picture of the conduction electron behavior in a weak localization regime. The aim of the present paper is to show that the novel coupling between magnons and conduction electrons results in a maximum in temperature dependent resistivity and is responsible for the nonmonotonous behavior of R(T), observed recently. The mechanism for coupling between magnons and conduction e... |
