Dielectric and magnetocaloric study of TmCrO$$_{3}$$

Yoshii, Kenji; Ikeda, Naoshi*

Dielectric and magnetocaloric measurements are carried out for the chromite TmCrO$$_{3}$$. This oxide was reported to be multiferroic below the N$'e$el temperature ($$T_{rm N}$$) 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 $$T_{rm N}$$. The magnetocaloric effect shows that the magnetic transitions at $$T_{rm N}$$ as well as the spin reorientation temperature are of a second order. This result strongly suggests the absence of magnetostructural transition at $$T_{rm N}$$ in accord with no observation of ferroelectric transition at this temperature.

Epitaxial transformation of hcp-fcc Ti sublattices during nitriding processes of evaporated-Ti thin films due to nitrogen-implantation

Chen, Y.*; Feng, X.*; Kasukabe, Yoshitaka*; Yamamoto, Shunya; Yoshikawa, Masahito; Fujino, Yutaka*

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$$_{2}$$$$^{+}$$ ions with 62 keV are implanted into as-deposited Ti films which consist of hcp-Ti and TiH$$_{x}$$ with preferred orientations, in the 400 kV analytic high resolution TEM combined with ion accelerators at JAEA Takasaki. Thus, titanium nitride (TiN$$_{y}$$) films with preferred orientations are epitaxially formed by the inheritance of partial atomic arrangement of hcp-Ti or TiH$$_{x}$$ 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.

Fast and real-time observation of hydrogen absorption kinetics for palladium nanoparticles

Matsumura, Daiju; Okajima, Yuka*; Nishihata, Yasuo; Mizuki, Junichiro

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.
