中性子回折による酸化物磁性体の磁気構造解析

摘要

The Japan proton accelerator research complex (J-PARC) will become operation in December 2008. A beam line for the industrial applications has been provided with equipment for material and the life science experiments, and a neutron diffractometer has become available for research on and development of practical materials. Magnetic structural information such as the distribution of magnetic cations and the direction and size of magnetic moments can be derived from neutron diffraction profiles. In this paper, the analytical results of the neutron diffraction of spinel ferrites, garnet ferrites, and hexagonal ferrites, which have been widely investigated as practical materials, are described for the benefit of researchers who wish to study the neutron diffraction.
