Abstract

A method of fabricating in-plane or out-of-plane thin-film multi-axial magnetic anisotropy devices is provided that includes either depositing a magnetic material with perpendicular or partially perpendicular anisotropy patterned into a multi-directional, curved, or closed path or depositing a thin-film of magnetic material on a piezoelectric material, where the magnetic material is arranged in a pattern, depositing excitation electrodes on the piezoelectric material, where the excitation electrodes are arranged in a pattern, biasing the piezoelectric material, by applying a voltage across the excitation electrodes, where an electric field through the piezoelectric material is generated by the applied voltage across the excitation electrodes, where the piezoelectric material is biased by the electric field to provide stress to the magnetic material, where the stress rotates a magnetization of the magnetic material, and patterning the magnetic material into a multi-directional, curved, or closed path.
