CuAl2O4 is a normal spinel oxide having quantum spin, S=1/2 for Cu2+. It is a rather unique feature that the Cu2+ ions of CuAl2O4 sit at a tetrahedral position, not like the usual octahedral position for many oxides. At low temperatures, it exhibits

Abstract Uniform quasi-one-dimensional integer spin compounds are of interest as a potential realization of the Haldane conjecture of a gapped spin liquid. This phase, however, has to compete with magnetic anisotropy and long-range ordered phases, th

Based on our earlier hypothesis of weak nonlocality, we developed a method for calculating the temperature dependences of the width and specific energy of the interphase boundary for binary substitutional alloys, using the concentration dependence of

X-ray reflectometry (XRR) and X-ray photoelectron spectroscopy (XPS) measurements (core levels and valence bands) were made of Cu thin films that were prepared and coated by capping Ta layers with different thicknesses (5, 10, 15, 20, and 30 Å), and

This work proposes an approach for the calculation of equilibrium solubility limits in binary alloys, which is an alternative to approaches based on gradient expansions. The proposed approach rests on the description of alloys in terms of a weak nonl

We have investigated the spin and oxidation states of Co in Co3BO5 using x-ray magnetic circular dichroism (XMCD) and dc magnetic susceptibility measurements. At low temperatures, XMCD experiments have been performed at the Co K-edge in Co3BO5 and Co

The vacancy-flux-induced decomposition of an interphase boundary in substitutional alloys has been considered. The interphase boundary decomposition has been described using the nonequilibrium thermodynamics approach, which considers a heterogeneous
