  • Publication number: 20180096766
    Abstract: A soft magnetic alloy includes a main component of Fe. The soft magnetic alloy includes a Fe composition network phase where regions whose Fe content is larger than an average composition of the soft magnetic alloy are linked. The Fe composition network phase contains Fe content maximum points that are locally higher than their surroundings. A virtual-line total distance per 1 ?m3 of the soft magnetic alloy is 10 mm to 25 mm provided that the virtual-line total distance is a sum of virtual lines linking the maximum points adjacent each other. A virtual-line average distance that is an average distance of the virtual lines is 6 nm or more and 12 nm or less.

  • Publication number: 20180096765
    Abstract: A soft magnetic alloy includes a main component of Fe. The soft magnetic alloy includes a Fe composition network phase where regions whose Fe content is larger than an average composition of the soft magnetic alloy are linked. The Fe composition network phase contains Fe content maximum points that are locally higher than their surroundings in 400,000/?m3 or more. A ratio of Fe content maximum points whose coordination number is 1 or more and 5 or less is 80% or more and 100% or less with respect to all of the Fe content maximum points.

  • Publication number: 20180082772
    Abstract: A rare earth magnet includes main phase grains having an R2T14B type crystal structure. The main phase grains include Ga. A concentration ratio A (A=?Ga/?Ga) of the main phase grains is 1.20 or more, where ?Ga and ?Ga are respectively a highest concentration of Ga and a lowest concentration of Ga in one main phase grain.

  • Publication number: 20170221616
    Abstract: Provided is a sintered magnet that is an R-T-B based sintered magnet having a region having a concentration of at least one heavy rare earth element decreasing from the surface toward the inside, in which the at least one heavy rare earth element includes at least either of Tb or Dy, R includes Nd, T includes Fe, Co, and Cu, there is a grain boundary phase containing at least either of Tb or Dy and Nd between two main phase particles, and a value obtained by subtracting a half value width of a concentration distribution curve of Cu from a half value width of a concentration distribution curve of Tb or Dy in a part including the grain boundary phase is from 10 to 20 nm.
