| Outline of Final Research Achievements |
In magnetic materials lacking an inversion symmetry, unusual properties of off-diagonal responses take place, such as electric field induced magnetization or electric polarization induced by magnetic fields, which are originating in d-p and d-f parity mixing and Dzyaloshinskii-Moriya antisymmetric interaction. In this research, we have investigated microscopic ordered structures of three main substances using resonant x-ray diffraction. First, the electro-magnetic effects in SmRu4P12 exhibiting magnetic-field-induced charge order. Second, ordering of toroidal moments in the cycloidal magnetic structure of GdRu2Al10. Third, the formation of chiral magnetic soliton lattice in Yb(Ni,Cu)3Al9.
