    摘要： Disclosed is a magnetic material in which 50% by volume of the magnetic particles are accounted for by the main phase of the magnet, the main phase having a Curie temperature (Curie point) of 200° C. or higher, a saturation magnetic-flux density at around 20° C. of 1.0 T (tesla) or higher, and a coercive force of 10 kOe or higher, the crystal structure of the main phase being stable up to 200° C., and in which phases other than the main phase which are present at the grain boundaries or grain surfaces have stabilized or improved the magnetic properties. This magnetic material comprises two ferromagnetic phases, i.e., a ferromagnetic compound which is composed of fluorine, iron, and one or more rare-earth elements including yttrium and ferromagnetic iron which contains fluorine, carbon, nitrogen, hydrogen, or boron. A fluoride and an oxyfluoride have been formed at some of the boundaries or surfaces of the grains of the ferromagnetic phases.

    摘要： Characteristics of a magnetic material are improved without using a heavy rare earth element as a scarce resource. By incorporating fluorine into a magnetic powder and controlling the crystal orientation in crystal grains, a magnetic material securing magnetic characteristics such as coercive force and residual flux density can be fabricated. As a result, the resource problem with heavy rare earth elements can be solved, and the magnetic material can be applied to magnetic circuits that require a high energy product, including various rotating machines and voice coil motors of hard discs.

    摘要： A conventional method for forming an insulating film on a magnet has a difficulty in achieving sufficient improvement in magnetic characteristics due to nonuniformity of a coating film, and an extended time and higher temperature which are required in a thermal treatment. In order to solve the problems, the present invention provides a treating solution composed of an alcohol based solvent and a rare earth fluoride or alkaline earth metal fluoride dispersing in the solvent. In the treating solution, at least one X-ray diffraction peak has a half-value width larger than 1°. The present invention also provides a method for forming an insulating film using the treating solution.

    摘要： The object of the present invention is to provide a rare earth magnet which enables to achieve a good balance between high coercive force and high residual magnetic flux density, and its manufacturing method. The present invention provides a rare earth magnet in which a layered grain boundary phase is formed on a surface or a potion of a grain boundary of Nd2Fe14B which is a main phase of an R—Fe—B (R is a rare-earth element) based magnet, and wherein the grain boundary phase contains a fluoride compound, and wherein a thickness of the fluoride compound is 10 μm or less, or a thickness of the fluoride compound is from 0.1 μm to 10 μm, and wherein the coverage of the fluoride compound over a main phase particle is 50% or more on average. Moreover, after layering fluoride compound powder, which is formed in plate-like shape, in the grain boundary phase, the rare earth magnet is manufactured by quenching the layered compound after melting it at a vacuum atmosphere at a predetermined temperature, or by heating and pressing the main phase and the fluoride compound to make the fluoride compound into a layered fluoride compound along the grain boundary phase.
