Abstract: A ferrite sheet strip includes a strip shaped substrate and a plurality of ferrite sheet pieces provided on a surface of the substrate. The plurality of ferrite sheet pieces are aligned and spaced apart by a gap from one another along a longitudinal direction of the substrate. The gap extends at least partially so as not to be parallel to a lateral direction of the substrate.

Abstract: The present invention relates to ferrite particles for bonded magnets and a resin composition for bonded magnets which can provide a bonded magnet molded product capable of realizing a high magnetic force and a complicated multipolar waveform owing to such a feature that the ferrite particles are readily and highly oriented against an external magnetic field in a flowing resin upon injection molding, as well as a bonded magnet molded product obtained by injection-molding the above composition. According to the present invention, there are provided ferrite particles for bonded magnets which have a crystallite size of not less than 500 nm as measured in an oriented state by XRD, and an average particle diameter of not less than 1.30 μm as measured by Fisher method; a resin composition for bonded magnets; and a molded product obtained by injection-molding the composition.

Abstract: An object of the present invention is to enhance a coercive force of magnetic particles by promoting formation of a continuous R-rich grain boundary phase in a crystal grain boundary of a magnetic phase of the particles, and to thereby obtain R-T-B-based rare earth magnet particles further having a high residual magnetic flux density. The present invention relates to production of R-T-B-based rare earth magnet particles capable of exhibiting a high coercive force even when a content of Al therein is reduced, and a high residual magnetic flux density, in which formation of an R-rich grain boundary phase therein can be promoted by heat-treating Al-containing R-T-B-based rare earth magnet particles obtained by HDDR treatment in vacuum or in an Ar atmosphere at a temperature of not lower than 670° C. and not higher than 820° C. for a period of not less than 30 min and not more than 300 min.

Abstract: The present invention provides lithium nickelate-based positive electrode active substance particles having a high energy density which are excellent in charge/discharge cycle characteristics when highly charged, and hardly suffer from generation of gases upon storage under high-temperature conditions, and a process for producing the positive electrode active substance particles, as well as a non-aqueous electrolyte secondary battery. The present invention relates to positive electrode active substance particles each comprising a core particle X comprising a lithium nickelate composite oxide having a layer structure which is represented by the formula: Li1+aNi1−b−cCobMcO2 wherein M is at least one element selected from the group consisting of Mn, Al, B, Mg, Ti, Sn, Zn and Zr; a is a number of −0.1 to 0.2 (−0.1⋅a⋅0.2); b is a number of 0.05 to 0.5 (0.05⋅b⋅0.5); and c is a number of 0.01 to 0.4 (0.01⋅c⋅0.4); a coating compound Y comprising at least one element selected from the group consisting of Al, Mg, Zr, Ti and Si; and a coating compound Z comprising an Li element, in which a content of lithium hydroxide LiOH in the positive electrode active substance particles is not more than 0.40% by weight, a content of lithium carbonate Li2CO3 in the positive electrode active substance particles is not more than 0.65% by weight, and a weight ratio of the content of lithium carbonate to the content of lithium hydroxide is not less than 1.
