Abstract: A bond magnet includes filaments bonded with each other to form a shape of the bond magnet. Each of the filaments is a filamentous member including a resin material and magnetic powder dispersed in the resin material, and has magnetic anisotropy for high degree of freedom of magnetic flux direction and high surface magnetic flux density on a working surface.

Abstract: In a manufacturing method of a magnetic refrigeration material, a powder material made of La (Fe, Si)13 is molded by applying a pressure equal to or higher than 286 MPa and heating at a temperature equal to or lower than 600 degrees Celsius. Thus, a molded product of the magnetic refrigeration material is produced.

Abstract: A magnet manufacturing device includes a heater, a nozzle, a magnetic field application magnet and a stage. The heater heats a mixture of magnetic particles and a resin material. The nozzle has an internal flow passage that conducts the mixture while the resin material is molten. The nozzle has a discharge port which discharges the mixture and thereby forms each of a plurality of filaments. The magnetic field application magnet applies a magnetic field to the internal flow passage. The stage has a stage surface on which the plurality of filaments are placed. The discharge port is relatively movable with respect to the stage surface such that the plurality of filaments are stacked to form an arbitrary shape.
