摘要： In one embodiment, a magnet includes a plurality of layers, each layer having a microstructure of sintered particles. The particles in at least one of the layers are characterized as having preferentially aligned magnetic orientations in a first direction.

摘要： A method of forming a magnet includes forming a structure by electrophoretic deposition (EPD), and after forming the structure, sintering the formed structure to form a magnet. The forming the structure by EPD includes adding a plurality of first particles having magnetic anisotropy to an EPD chamber and applying a voltage differential across electrodes of the EPD chamber to create an electric field in the EPD chamber for causing electrophoretic deposition of the first particles above a first of the electrodes for forming a first layer comprising the first particles.
