Resumen:
FePd nanowires (NWs) with different compositions have
been grown into anodized aluminum oxide templates (AAO) by AC electrodeposition
at room temperature. The effects of nanowire composition and morphology on the
hysteresis properties of the ordered array of NWs are investigated. All the NWs
are polycrystalline; the Fe-rich wires have a structure while the Pd rich ones
are . FePd NWs are ferromagnetic and the spontaneous magnetization is found to
be parallel to the nanowire long axis (out of plane easy axis) and both, the
saturation polarization and the coercive field increase with the iron content
