Abstract
We have studied the Hall effect and the magnetoresistance in [110] textured Fe/Cr multilayers grown by electron beam evaporation. We have observed a strong magnetic field dependence of the Hall coefficient as well as a large magnetoresistance. In all cases the Hall voltage is positive. The ordinary Hall coefficient is positive at room temperature and changes sign at low temperatures; this is similar to the behavior of an antiferromagnet but differs from that observed in Fe-Cr alloys. The extraordinary Hall coefficient Rs is positive and varies with the resistivity ρ as Rs∝ρ2.6, suggesting the importance of interface scattering.Keywords
