要約(英語): The magnetic properties of Nd-Fe-B magnets with 0.5mm and 1mm cubes in size were measured with a vibrating sample magnetometer equipped with High Temperature Superconducting Magnet (VSM_HSC). With the VSM_HSC, high sweep speed and high accuracy in magnetization measurement were achieved. Furthermore, magnetic properties of Nd-Fe-B magnets were measured with the VSM_HSC, Pulsed Field Magnetometer and a Permeameter. It was found that the squareness of demagnetization curves appeared depending on the measurement systems.
