Interlayer Coupling in Magnetic/Pd Multilayers

Zhu-Pei Shi、Barry M. Klein1995-08-01arXiv

The Anderson model of local-state conduction electron mixing is applied to the p roblem of interlayer magnetic coupling in metallic multilayered structures with palladium (Pd) spacer layers. An oscillation period of $5$ spacer monolayers and the tendency towards ferromag netic bias of the interlayer magnetic coupling…

Mechanical properties of the binary titanium‐zirconium alloys and their potential for biomedical materials

Equo Kobayashi、Shigeru Matsumoto、Hisashi Doi 等 5 位作者1995-08-01Journal of Biomedical Materials Research

Mechanical properties of titanium-zirconium binary alloys were investigated in order to reveal their possible use for new biomedical materials and to collect useful data for alloy design through a hardness test, a tensile test, and optical microscopy. The hardness of the alloy containing 50% zirconium was approximatel…

Polaronic relaxation in perovskites

O. Bidault、Mario Maglione、M. Actis 等 5 位作者1995-08-01Physical review. B, Condensed matter

We report a low-temperature loss anomaly in several oxidic perovskites such as ${\mathrm{KTaO}}_{3}$, ${\mathrm{KTaO}}_{3}$:Nb, ${\mathrm{SrTiO}}_{3}$, ${\mathrm{SrTiO}}_{3}$:Ca, ${\mathrm{PbTiO}}_{3}$:La, Cu, and ${\mathrm{BaTiO}}_{3}$:La. We show that this anomaly arises from a low-frequency dielectric relaxation. T…

Kinetic structure of a two-dimensional liquid

M. M. Hurley、Peter Harrowell1995-08-01OpenAlex

On an intermediate time scale, a molecular dynamics simulation of a two-dimensional (2D) liquid of soft disks exhibits dramatic structural and kinetic inhomogeneities. We introduce a local relaxation time (defined as the time required for a particle to first travel a distance r from its initial position) in order to p…

Cathodoluminescence microcharacterization of the defect structure of quartz

M. A. Stevens Kalceff、Matthew R. Phillips1995-08-01OpenAlex

Cathodoluminescence (CL) spectroscopy has been used to investigate the irradiation-sensitive defect structure of ultrapure synthetic quartz at 295 and 80 K. CL emissions are identified with particular defect centers. Insight into the processes of defect formation and subsequent electromigration resulting from the trap…
