San Jose, California)We 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 =0.7) and a minimum at =0.5. These results are discussed in terms of the dipolar coupling between both phases.engHysteresis and relaxation of hard–soft nanocomposite samplesjournal articlehttp://dx.doi.org/10.1063/1.373150http://aip.scitation.orgopen access538.9CoercivityFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
