摘要： An anisotropic thin-film rare-earth permanent magnet endowed with high magnetic characteristics by rendering a vapor-phase-grown thin film anisotropic in the layering direction. The atomic laminate units are formed by laminating a monoatomic layer of a rare earth element on a substrate of a non-magnetic material having, a flat smoothness and then by laminating an atomic laminate of a transition metal element having a plurality of monoatomic layers of a transition metal element, so that the atomic laminate units of a characteristic construction are laminated in a plurality of layers. As a result, each atomic laminate of the transition metal element has an easy magnetizable axis in the laminate direction of the monoatomic layers and which are sandwiched between a monoatomic layer of a rare-earth element so that an inverse magnetic domain is suppressed to establish a strong coercive force. Moreover, the content of the transition metal element to the rare-earth metal is raised to improve the residual magnetic flux density drastically.

摘要： A ferrite magnet obtained by adding a ferrite having a hexagonal W-type magnetoplumbite structure to a ferrite having a hexagonal M-type magnetoplumbite structure, in which a portion of Sr, Ba, Pb or Ca is replaced with at least one element that is selected from the group consisting of the rare-earth elements (including Y) and Bi and that always includes La, during the fine pulverization process thereof.

摘要： A rare earth metal-based permanent magnet has a film layer formed substantially of only a fine metal powder on a metal forming the surface of the magnet. The rare earth metal-based permanent magnet having the film layer on its surface is produced in the following manner: A rare earth metal-based permanent magnet and a fine metal powder forming material are placed into a treating vessel, where both of them are vibrated and/or agitated, whereby a film layer made of a fine metal powder produced from the fine metal powder producing material is formed on a metal forming the surface of the magnet. Thus, the formation of a corrosion-resistant film such as plated film can be achieved at a high thickness accuracy by forming an electrically conductive layer uniformly and firmly on the entire surface of the magnet without use of a third component such as a resin and a coupling agent.

The magnet is a sintered magnet that has been magnetized to a permeance coefficient of 0.5 or more and that has a coercivity HcJ of 1.6 MA/m or more.
