AbstractWe present experimental results on the hysteresis and relaxation of Fe/Ba hexaferrite composite samples prepared by ball milling starting from precursor Fe and Ba hexaferrite particles. Our results show that, for maximum applied fields of up to 8 kOe, the measured loops show a shift of up to 85 Oe. The compositional dependence of that loop displacement presents two maxima (at approximately x = 0.3 and x = 0.7) and a minimum at x = 0.5. These results are discussed in terms of the dipolar coupling between both phases.
