Crystal and magnetic structures of the title hard magnets were determined by means of neutron and X-ray powder diffraction measurements. A high-resolution diffractometer, JRR3M-HRPD, was utilized for the measurements done at temperatures in the range from 15K to ambient. Rietveld profile-fitting technique was applied for the analysis. It is demonstrated that reliable structural parameters and magnetic moments of magnetic atoms can be determined reasonably for the above complicated crystal systems.
