Patent number: 9111674Abstract: The present invention provides a permanent magnet whose magnetic properties will not be significantly decreased and which is excellent in the temperature properties compared to the existing R-T-B based permanent magnet. In the R-T-B based structure, a stack structure of R1-T-B based crystallizing layer and (Y,Ce)-T-B based crystallizing layer can be formed by alternatively stacking R1-T-B and (Y,Ce)-T-B. In this way, a high magnetic anisotropy field of the R1-T-B based crystallizing layer can be maintained while an improved temperature coefficient of the (Y,Ce)-T-B based crystallizing layer can be obtained. Further, a high coercivity can be obtained by adding the Ce-T-B based crystallizing layer with a low lattice distortion to the Y-T-B based crystallizing layer.Type: GrantFiled: April 21, 2014Date of Patent: August 18, 2015Assignee: TDK CORPORATIONInventors: Ryuji Hashimoto, Kenichi Suzuki, Kyung-Ku Choi

Publication number: 20150070005Abstract: A magnetic measurement device which measures coercivity and coercivity distribution in a microregion of a thin plate magnetic sample with high coercivity. A magnetic sample is applied with a magnetic field in a first direction and magnetized, a second magnetic field is applied in a direction opposite to the first, a measuring part scans the sample, measuring magnetic flux leakage due to remnant magnetization in the sample. The intensity of the second magnetic field is gradually increased while the measuring part repeats the measurement to obtain the second magnetic field wherein the magnitude of the leakage from the sample reaches the maximum level, and when a magnetic field equivalent to the coercivity is applied to the sample and about half of the magnetization is reversed, the sample's coercivity is obtained based on the determination that the demagnetizing field Hd reaches the minimum level and the leakage reaches the maximum level.Type: ApplicationFiled: December 13, 2012Publication date: March 12, 2015Inventors: Kenichi Suzuki, Tsutomu Chikamatsu, Akio Ogawa, Kyung-ku Choi, Ryuji Hashimoto
