    Abstract

    We show that in granular normal-ferromagnetic metals the giant magnetothermopower is related to the giant magnetoresistance as it is a result of the interplay between the spin-dependent elastic scattering (responsible for magnetoresistance effect) and the inelastic spin mixing scattering on magnetic clusters. For a small change of resistance of sample in an applied magnetic field the variation of the thermopower is connected linearly with the giant magnetoresistance and both are proportional to the square of the sample magnetization.
