The purpose of the present invention is to present a thin-plate magnet with a fine crystalline structure that is 70 mu m to 500 mu m thick, making miniature, thin magnetic circuits possible, and has, as cast, an inherent coercive force iHc of 2.5 kOe or higher and residual magnetic flux density of 9 kG or higher and a performance-to-cost ratio rivaling that of hard ferrite magnets when Nd-Fe-B fine crystalline permanent magnets with a low rare earth content that are a mixture of a soft magnetic phase and a hard magnetic phase are produced. iHc can be increased to 2.5 kOe or higher and the optimum roll circumferential speed range within which hard magnetic properties are realized can be expanded when compared to the conditions under which Nd-Fe-B ternary magnets are produce, while at the same time, a fine crystalline permanent magnet alloy with a thickness of 70 mu m to 500 mu m is obtained, by using an alloy melt with a specific composition to which Co, Cr, Mn, Ni, Cu, Ga, Ag, Pt, Au, or Pb has been added during the process whereby a fine crystalline permanent magnet alloy having a fine crystalline structure of 15 nm to 50 nm is produced directly from an alloy melt by continuously casting the alloy melt on a cooling roller that is rotating in an inert gas atmosphere under reduced pressure of 30 kPa or less.

The present invention is presented with the object of providing a manufacturing method for thin-plate magnets that, as cast, exhibit an intrinsic coercive force iHc of 2.5 kOe or greater and a residual magnetic flux density Br of 9 kG or greater, exhibit a performance-to-cost ratio comparable to hard ferrite magnets, and exhibit a fine crystalline structure with a thickness of 70 to 500 mu m wherewith magnetic circuits can be made smaller and thinner. By employing alloy melts to which specific elements have been added, in a process wherein alloy melts of specific composition are continuously cast on a rotating cooling roller or rollers in a reduced-pressure inert or inactive gas atmosphere at 30 kPa or less, and fine crystalline permanent magnets having a fine crystalline structure of 10 to 50 nm are fabricated, fine crystalline permanent magnets having a thickness of 70 to 500 mu m can be obtained wherein iHc is improved to 2.5 kOe or greater, and the ideal roller circumferencied speed range wherein hard magnetic properties are manifested can be broadened as compared to the conditions under which Nd-Fe-B ternary magnets are fabricated

A flexible permanent magnet containing atomized, generally spherical rare earth magnet particles bonded in a binder resin including a nitrile rubber and precipitated amorphous silica. The bonded permanent magnet exhibits high mechanical flexibility and elasticity, good magnetic properties, and good heat aging, and the magnet powder may be mixed with the binder resin with little to no risk of combustion. In an exemplary embodiment, a permanent magnet composition includes a nitrile rubber with about 23-37% acrylonitrile content, an ethylene vinyl acetate copolymer, a precipitated amorphous silica, and atomized, generally spherical rare earth magnet particles having a size distribution including a median particle size in the range of about 35-55 mum with a standard deviation in the range of about 10-30 mum and less than about 0.1% of the particles having a diameter above about 115 mum. Bonded permanent magnets of the present invention exhibit a percent ultimate elongation greater than about 100%, and even greater than about 200%, thereby providing at least a 10-fold improvement in elasticity concurrently with good magnetic properties.
