The temperature-depedence of resistivity and magnetoresistance for as-cast and annealed samples of amorphous thin ribbons of [Fe86Zr7Cu1B6] have been investigated trouugh the sample by Joule heating. The temperature coefficients of the resistivity show a large difference between the as-cast and Joule heated samples, the effect which originated by the nano-crystallizations. The observed negative magnetoresistance is proportional to the square of the magnetization. The s - d type exchange constant was estimated at J = 0.1 eV, the analysis being based on a model of the conduction carrier scattering by exchange interactions with differntly oriented spins in magnetic domain structures.
