Publication number: 20240153680Abstract: Provided is a rare-earth anisotropic magnet powder capable of achieving high magnetic properties while reducing the usage of Nd and Pr. The present invention provides a rare-earth anisotropic magnet powder comprising magnetic particles that contain rare-earth elements, boron, and a transition metal element. The rare-earth elements include a first rare-earth element that comprises Ce and/or La and a second rare-earth element that comprises Nd and/or Pr. The rare-earth elements have a first ratio (R1/Rt) of 5% to 57%. The first ratio (R1/Rt) is a ratio of an amount (R1) of the first rare-earth element to a total amount (Rt) of the rare-earth elements in terms of the number of atoms. The first rare-earth element has a La ratio (La/R1) of 0% to 35%. The La ratio (La/R1) is a ratio of an amount of La to the amount (R1) of the first rare-earth element in terms of the number of atoms. The magnetic particles have a Ga content of 0.35 at % or less with respect to 100 at % as a whole.Type: ApplicationFiled: March 3, 2022Publication date: May 9, 2024Applicants: AICHI STEEL CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Ryo SHIMBO, Masao YAMAZAKI, Noritsugu SAKUMA, Akihito KINOSHITA, Akira KATO, Tetsuya SHOJI
