Abstract: A magnetic measurement device which can measure the magnetic characteristics in a microregion of a thin plate magnetic sample. After a magnetic sample is applied by a magnetic field and magnetized accordingly, by scanning the magnetic sample using a measuring part, the magnetic flux leakage in the magnetic sample can be measured. The magnetic flux leaks outside by magnetizing a first region and a second region of the magnetic sample in reciprocally opposite directions and reducing the demagnetizing field. Specifically, a magnetic field generating part with at least a pair of magnetic poles is used to perform the magnetization of multiple poles, or the magnetic field generating part applies a damped oscillation magnetic field to perform the magnetization, or a local magnetic field generating part which applies an alternating magnetic field and scans the surface of the sample at the same time is used to perform the magnetization.

Abstract: An R-T-B based magnet as raw material undergoes heating treatment for a long time and main phase grains turn core-shell like. The R-T-B based magnet includes main phase grains having core and shell portions that covers the core. When the mass concentration of R1 and Y in the core portion is set as ?R1 and ?Y respectively and the mass concentration of R1 and Y in the shell portion is set as ?R1 and ?Y respectively, the ratio (B/A) between the mass concentration ratio of R1 to Y in the shell portion (?R1/?Y=B) and the mass concentration ratio of R1 to Y in the core portion (?R1/?Y=A) is 1.1 or more. Thus, the decrease of coercivity caused by Y addition is prevented, and the increase effect of temperature characteristics caused by addition of Y will lead to improve the magnetic properties under high temperature.

Abstract: The present invention provides such a permanent magnet that its magnetic properties will not significantly decrease and it can be prepared at a lower temperature, compared to conventional R-T-B based permanent magnets. In the R-T-B based structure, a stacked structure of R1-T-B based crystal layer and Ce-T-B based crystal layer can be formed by alternatively stacking the R1-T-B based crystal layer and the Ce-T-B based crystal layer. In this way, a high magnetic anisotropy field of the R1-T-B based crystal layer can be maintained while the crystallization temperature can be lowered by the Ce-T-B based crystal layer.

Abstract: 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.
