  • Abstract
    Arrays of Ni nanowires have been studied by means of first order reversal curves (FORC) diagrams. The dependence of the coercivity of the arrays as a function of the length of the nanowires has been experimentally investigated. We have shown that the FORC diagrams provide detailed information about the distribution of interactions and coercivities and allowed us to observe the reversible component of magnetization. Our results are in good agreement with analytical calculations obtained by means of a simple model.
