Anisotropy of Magnetization Reversal and Magnetoresistance in Square   Arrays of Permalloy Nano-Rings
  Magnetization reversal mechanisms and impact of magnetization direction are studied in square arrays of interconnected circular permalloy nanorings using MOKE, local imaging, numerical simulations and transport techniques.
