Systematic Mn d-configuration change in theLa1−xCaxMnO3system: A Mn K-edge XAS study

Systematic Mn K-edge x-ray-absorption spectroscopy (XAS) measurements on samples of ${\mathrm{La}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Ca}}_{\mathrm{x}}$${\mathrm{MnO}}_{3}$ are reported. Detailed results on the chemical shift and pre-edge feature spectral strength (both indicators of the Mn d-hole count) a…

Structural, magnetic, and transport properties of the giant magnetoresistive perovskitesLa2/3Ca1/3Mn1−xAlxO3−δ

The effect of the substitution for Mn with Al in the magnetoresistive perovskite ${\mathrm{La}}_{2\mathrm{/}3}$${\mathrm{Ca}}_{1\mathrm{/}3}$${\mathrm{MnO}}_{3}$ has been studied by preparing the series ${\mathrm{La}}_{2\mathrm{/}3}$${\mathrm{Ca}}_{1\mathrm{/}3}$${\mathrm{Mn}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$${\m…

Magneto-optical effect in the weak ferromagnetsLaMO3(M= Cr, Mn, and Fe)

It is shown that antiferromagnetic spin order coupled through the spin-orbit interaction with the lattice distortion can lead to a nonvanishing ferromagnetic component of the orbital magnetization and strong optical nonreciprocity in transition-metal perovskite oxides with orthorhombic structure. This magneto-optical…

Effects of Adding Copper(II) Salt to Organosulfur Cathodes for Rechargeable Lithium Batteries

We report the preliminary analysis of a new cathode material and the performance of secondary lithium cells which contain it. The material is comprised of an organosulfur compound, 2,5‐dimercapto‐1,3,4‐thiadiazole (DMcT), doped with a copper(II) salt in a poly(aniline) matrix. Secondary lithium cells which use this ma…
