The antiferromagnetic ordered phase below $$T_{rm MI}$$ = 16.5 K and the unresolved intermediate phase between $$T_{rm MI}$$ and $$T^*$$ (= 14 K) in SmRu$$_4$$P$$_{12}$$ have been studied by resonant and nonresonant X-ray diffraction. In the intermediate phase, nonresonant Thomson scattering with $$q$$ = (1,0,0) is induced by applying a magnetic field. This phenomena is caused by atomic displacements reflecting the charge order in the $$p$$ band, as predicted theoretically. Simultaneously, the antiferromagnetic moment of Sm is enhanced along the field direction, which is considered to reflect the staggered ordering of the $$Gamma_7$$ - $$Gamma_8$$ crystal-field states. The present results show that the orbital-dependent $$p$$ - $$f$$ hybridization in association with the nesting instability in the $$p$$ band gives rise to the unconventional charge order similarly with PrRu$$_4$$P$$_{12}$$ and PrFe$$_4$$P$$_{12}$$.

Muon spin relaxation in PrRu$$_4$$P$$_{12}$$

In filled skutterudite structural system PrRu$$_4$$P$$_{12}$$, many studies are paid attention on the electronic state of the Pr ion from several point of view, including multipole state. Recently, it was proposed that the complex state of nucleous spin of Pr and Pr 4f electron is formed and this complex state makes some effect on the properties of the system. We have studies muon spin relaxation experiment to elucidate the magnetic properties of PrRu$$_4$$P$$_{12}$$ down to low temperatures. We will report the detail of the results.

$$mu$$SR study on Ce(O$$_{1-x}$$F$$_x$$)BiS$$_2$$

Recently, it was discovered that relatively high superconducting transition temperature, T$$_csim$$10K, in layered structural system Ln(O$$_{1-x}$$F$$_x$$)BiS$$_2$$ and many studies have been carried out to clarify the nature of its superconductivity. In some system, novel behaviors were reported. For example, in Ce(O$$_{1-x}$$F$$_x$$)BiS$$_2$$ with x=0.5, superconductivity and ferromagnetism observed simultaneously. Meanwhile, in x=0 system, Kondo like behavior in temperature dependence of the specific heat without carrier was found. To clarify these behaviors, we are studying Ce(O$$_{1-x}$$F$$_x$$)BiS$$_2$$ by using $$mu$$SR technique and found that ferromagnetism is not intrinsic behavior.

SmAu$$_{3}$$Al$$_{7}$$ exhibits antiferromagnetic order near 2.8 K at atmospheric pressure. The specific heat C/T is a heavy electron system with a low temperature of 2J/molK$$^{2}$$ or more. This heavy electronic state is insensitive to magnetic field. In particular, this compound is characterized in that the heavy electronic state depends on the magnetic field direction. However, it is also interesting that the valence of Sm does not seem to be mixed valance state only in 3+ state according to XAS. Therefore, in this study, we attempted to estimate the temperature and magnetic field direction dependence of magnetic fluctuations using Al-NMR. This time, we discuss spin lattice relaxation time.
