摘要: In a method for producing a resin-bonded rare earth-iron-boron magnet, a powder is subjected to a heat-treatment below its melting point. The powder can be either: (1) a mixture of both: (a) a powder of a rare earth-iron-boron magnetic alloy comprising about 8 to about 30 atomic percent of R, which stands for at least one selected from the group of Y (yttrium) and rare earth elements, about 2 to about 28 atomic precent of B(boron), and at least 50 atomic percent of Fe(iron) and (b) at least one of the group consisting of R, R-oxides, which are oxides of R, and R-compound, which are the compounds consisting essentially of more than 30 atomic percent of R and the balance substantially of at least one of Fe and Co; or (2) a rare earth-iron-boron magnetic alloy comprising about 8 to about 30 atomic percent of R, about 2 to about 28 atomic percent of B, about 0.1 to about 13 atomic percent of Ga, and at least 50 atomic percent of Fe. The resultant heat-treatment powder is then bonded with a resin. The present invention also includes a magnet such as might be made by such a method.

摘要: Disclosed herein is a planar magnetic element comprising a substrate, a first magnetic layer arranged over the substrate, a first insulation layer arranged over the first magnetic layer, a planer coil formed of a conductor, having a plurality of turns, arranged over the first insulation layer and having a gap aspect ratio of at least 1, the gap aspect ratio being the ratio of the thickness of the conductor to the gap between any adjacent two of the turns, a second insulation layer arranged over the planar coil, and a second magnetic layer arranged over the second insulation layer. When used as an inductor, the planar magnetic element has a great quality coefficient Q. When used as a transformer, it has a large gain and a high voltage ratio. Since the element is small and thin, it is suitable for use in an integrated circuit, and can greatly contribute to miniaturization of electronic devices.
