A Study of Spin and Orbital Magnetic Form Factors of CeRh3B2 by X-Ray Magnetic Diffraction
An experimental method of X-ray magnetic diffraction was applied to the ferromagnetic rare-earth compound CeRh3B2, and its spin and orbital magnetic form factors were measured independently for the first time. Our curve-fitting analysis shows that the orbital magnetic form factor is reproduced by the calculated atomic-model form factor of Ce-4f electrons under the dipole approximation. The comparison of the sum of form factors and the total magnetic form factor measured by the polarized neutron diffraction reveals anisotropic distribution of the magnetic moment in real space.
