Skew scattering and side jump mechanisms in the Hall effect of amorphous NdFeB/FeB compositionally modulated multilayers

Hall-effect measurements have been performed in amorphous sputtered Nd/sub 12/Fe/sub 80/B/sub 8/ film and in amorphous sputtered Nd/sub 26/F/sub 68/B/sub 6//Fe/sub 92/B/sub 8/ multilayers between 4.2 and 200 K with applied magnetic fields up to 7 T. The layered character of the samples has been tested by X-ray diffraction. The dependence of resistivity and saturation magnetization on layer thicknesses makes it possible to investigate the contribution of the different microscopic mechanisms to the Hall effect. The Hall-effect data show the typical behaviour of an itinerant ferromagnet with skew and side jump terms.<
