Claim 7:
8. A method of processing an anisotropic permanent magnet comprising:
forming anisotropic flakes from a bulk magnet alloy of Al-Ni-Co material, the anisotropic flakes each having a selected orientation with an easy magnetization direction;
combining the anisotropic flakes with a binder to form a mixture;
extruding or rolling the mixture to align the mixture according to the selected orientation without applying a magnetic field to form one or more anisotropic layers of anisotropic flakes having a collective magnetization direction based on the easy magnetization directions;
producing the anisotropic permanent magnet from the layers having the collective magnetization direction such that the anisotropic permanent magnet has a magnetization with a specific orientation; and
sintering the anisotropic permanent magnet to remove the binder to increase an intensity of the magnetization of the anisotropic permanent magnet without changing the collective magnetization direction.
