Times Cited Count:6 Percentile:60.45(Chemistry, Physical)Dielectric and magnetocaloric measurements are carried out for the chromite TmCrO. This oxide was reported to be multiferroic below the N
el temperature (
) of 125 K, likely due to a structural transformation. The dielectric response shows large dielectric constants below 300 K. However, from the analyses of loss tangent, AC conductivity and dielectric modulus, this behavior is rooted in hopping of charge carriers rather than electric dipoles, as proposed for some other chromites. No dielectric anomaly is found at
. The magnetocaloric effect shows that the magnetic transitions at
as well as the spin reorientation temperature are of a second order. This result strongly suggests the absence of magnetostructural transition at
in accord with no observation of ferroelectric transition at this temperature.

Times Cited Count:0 Percentile:0.01(Chemistry, Physical)Epitaxial transformation processes of titanium films due to Nitrogen-implantation have been clarified through in-situ observations by using transmission electron microscope(TEM)and electron energy loss spectroscope, along with molecular orbital calculations. The N ions with 62 keV are implanted into as-deposited Ti films which consist of hcp-Ti and TiH
with preferred orientations, in the 400 kV analytic high resolution TEM combined with ion accelerators at JAEA Takasaki. Thus, titanium nitride (TiN
) films with preferred orientations are epitaxially formed by the inheritance of partial atomic arrangement of hcp-Ti or TiH
in as-deposited Ti films and by the occupation of octahedral sites by N atoms, which elucidates that epitaxial transformation of hcp-fcc Ti sublattices occurs.

Times Cited Count:9 Percentile:51.86(Chemistry, Physical)Dynamical structural change of Pd nanoparticles during hydrogen absorption was directly observed by X-ray absorption fine structure with dispersive optics. Hydrogen pressure dependence of the expansion of the interatomic distance in Pd nanoparticles was estimated by real-time-resolved observation with a rate of 50 Hz. It has been revealed that the Pd nanoparticles show strong hydrogen pressure dependence of the reaction rate. Determined reaction order implies that the surface dissociative adsorption process is the key issue for the hydrogen storage kinetics.

Times Cited Count:3 Percentile:27.19(Chemistry, Physical)The alloying behavior of transition metals (TMs) in solid -phase uranium (
-U), which is expected to be used as fuel for next-generation nuclear reactors, is investigated using the discrete-variational Dirac-Fock-Slater molecular orbital method. Using a model cluster, U
/TM, as the minimum unit of
-U/TM alloys, we evaluate the d-orbital energy of the TM (Md), the bond order between the TM and U atoms, and the orbital overlap population (OOP) between the atomic orbitals of the TM and U atoms. We subsequently examine the effect of these quantities on the maximum solid solubility (MSS) of the
-U/TM alloys. Md and the OOP (U 6d-TM d) exhibit good correlations with the MSS for
-U/TM alloys, so that the interaction between the U-6d and TM-d atomic orbitals is found to play a key role in determining the MSS of the
-U/TM alloys. The magnitude of the MSS can be explained in terms of the stabilization energy caused by U 6d-TM d orbital interactions for
-U/TM alloys, which is affected by the Md and the OOP. The exponential dependence of the MSS on Md and the OOP is explained in terms of the equilibrium constant obtained using a substitution cluster model for
-U/TM alloys. We also map the MSS of
-U/TM alloys using the Md and the OOP as the alloying parameters. These results will assist the quantum design of nuclear fuel materials for other alloy systems besides the present alloy system.
