    摘要: An appropriate ferromagnetic substance, whose magnetization arises mainly from samarium, is selected, and the composition of this ferromagnetic samarium substance is, according to necessity, modified by an atomic substitution or addition; whereby the two parts of the magnetization originating from the orbital magnetic moment and the spin one compensate with each other and the resultant total magnetization becomes close to zero. An external magnetic field is applied to this ferromagnetic samarium substance at a temperature, where it has a finite magnetization, so as to align the electron spin polarization therein over a macroscopic range, and, subsequently, the temperature is set to be the magnetization-compensation temperature and the applied field is reduced to be nearly zero; whereby this ferromagnetic samarium substance can have a specific property. Since this property is useful to generate a spin-polarized charged-particle beam, to measure the spin polarization, and to polarize or analyze the spin for a charged-particle flow (an electric current), this ferromagnetic samarium substance can be a material for a spin-resolving device.
