hybridization gap could be not necessary to form the unusual AFM order. The pressure effects on the magnetic susceptibility is also studied. We discuss a difference in the pressure response of the magnetic susceptibility based the electronic state between x = 0 and 0.1.

We study the -type antiferro-octupole (AFO) ordered state of Ce
La
B
below 1.5 K by resonant X-ray diffraction in magnetic fields. Multipole moments induced by the field in the AFO phase are identified. In a mean-field model for the
AFO order within the
quartet crystal-field ground state, the
and
antiferroquadrupoles (AFQ) are expected as mostly induced AFQ. However, in contrast to this expectation, the main induced moment is found to be the
-type AFQ.

Times Cited Count:14 Percentile:49.82(Materials Science, Multidisciplinary)The multipole ordered phase in CeLa
B
(phase IV) has been studied by resonant X-ray diffraction in magnetic fields. By utilizing diamond X-ray phase plates to rotate the incident linear polarization and a conventional crystal analyzer system, full linear polarization analysis has been performed to identify the order parameters. The analysis shows that the
quadrupoles are more induced by the field than the
quadrupoles in phase IV, in disagreement with mean-field calculations, in which the
quadrupole is the main induced moment. Hence, we consider that large fluctuations of the
quadrupole is hidden behind the primary ordering of the octupole.

Times Cited Count:10 Percentile:54.72(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to
collisions.

Times Cited Count:2 Percentile:65.67(Physics, Applied)The diffusion of positive muon in condensed matter has been investigated for many years by using
spin rotation/relaxation (
SR) technique. The
SR studies have provided deep insight into quantum diffusion at low temperatures as well as hopping process at high temperatures, which are closely related to hydrogen dynamics in the dilute limit. We here report transverse field (TF)
SR studies of the
diffusion in cubic
-electron compounds PrPb
and SmAg
In. The
site splits into two magnetically labeled sites when high TF is applied to single-crystalline specimens along the [001] direction. The
SR lines show drastic variation according to the
motion between the magnetically labeled sites. From detailed analysis of the
SR lines, we deduced
hopping parameters for both compounds.

We have investigated the electronic structures of Pt/YFe
O
thin films irradiated by gamma ray and heavy particles. Investigating details of this system is interesting from a possible application of waste heat recovery using the spin Seebeck effect (SSE) due to a tolerance against a presence of atomic defect. Irradiation of
Co gamma ray does not affect the spectral profiles such as Fe 2
, a fact being consistent with the gamma-ray tolerance of SSE as reported previously. On the other hand, the irradiation of Au particles was found to lead to a chemical shift of some photoelectron peaks, suggesting a possible defect of some ions such as Fe
.
