Coercivity and the Figure of Merit of Irregular Triangular Ferromagnetic Nanowire Arrays

Abstract

The magnetostatic interaction, the coercivity and the figure of merit of an irregular triangular nanowire array are studied with the help of Neel model. The results show that the broadening of the distribution of nanowire lengths decreases the thermal stability of the array and the minimum figure of merit is a good candidate for measuring the system’s thermal stability.
