PHYSICAL REVIEW B   97(18) 184417-1-15   May 2018   [Refereed]
We investigated the physical properties of CexLa1-xB6 at x similar to 0.8, below which the T-beta-type antiferro-octupole (AFO) ordered phase IV appears as a result of the larger suppression rate of T-Q than T-N by La doping. The most important re...

The La-substitution and pressure effects on antiferromagnet CeCoSi with a tetragonal crystal structure were investigated in order to clarify the origin of the pressure induced ordered phase (PIOP) with an enormously high transition temperature of ...

We have performed resonant X-ray diffraction experiments on the antiferromagnet GdRu2Al10 and have clarified that the magnetic structure in the ordered state is cycloidal with the moments lying in the bc-plane and propagating along the b-axis. The...

PHYSICAL REVIEW B   94(18)    Nov 2016   [Refereed]
Structural properties of SmRu4P12 in the anomalous magnetic ordered phase between T* similar to 14 K and T-N = 16.5 K in magnetic fields has been studied by x-ray diffraction. Atomic displacements of Ru and P, reflecting the field-induced charge o...
