Granular Co-Nanowires

Magnetization reversal of three interacting Co-nanowires. The external field is applied perpendicular to the long axis. The colors represent the magnetization parallel to the external field. The magnetization starts to rotate in the smaller grains with a magnetocrystalline easy direction parallel to the long axis. Magnetization reversal of three interacting Co-nanowires.
