Claim 0:
1. A method of processing an anisotropic permanent magnet comprising:
forming anisotropic flakes from a bulk magnet alloy of Al-Ni-Co material, each of the anisotropic flakes having a selected orientation with an easy magnetization direction with respect to a surface of the flake;
combining the anisotropic flakes with a binder to form a mixture;
extruding or rolling the mixture without applying a magnetic field or any prior application of a magnetic field to align the anisotropic flakes such that the easy magnetization directions of the anisotropic flakes align via mechanical processing to form one or more layers having an overall magnetization direction aligned with the easy magnetization directions of the anisotropic flakes based on the selected orientation; and
producing the anisotropic permanent magnet from the layers having the magnetization direction such that the anisotropic permanent magnet has a magnetization with a specific orientation.
