摘要：

Nanowire arrays are characterized using ferromagnetic resonance (FMR) experiments. The dipolar interactions between nanowires are studied by investigating the angular variation of the FMR resonant field. Two qualitatively different angular variations in the resonant field are experimentally observed and explained using the interaction field. The experimental data are explained using a theoretical model that considers the interaction field in nanowire networks as arising from magnetic charges at the wire's surface (wire's extremities and lateral cylindrical surface) and takes into account the finite wire length and porosity of the sample.
