Abstract: We have investigated the evolution of magnetic spin states and in-plane magnetic anisotropy in arrays of elongated Ni80 Fe20 rings. Large area (4×4 mm2) elongated Ni80 Fe20 nanorings of thickness in the range from 5 to 60 nm were fabricated using deep ultraviolet lithography at 248 nm exposing wavelength. The magnetic spin states and the magnetization reversal processes are strongly dependent on the ring thickness and in-plane magnetic anisotropy due to the elongation of the rings. Our experimental results are in a very good agreement with micromagnetic simulations. © 2005 American Institute of Physics.
