Synergistic Modulation of Magnetic and Dielectric Properties via La‐V Co‐Substitution in Barium Hexaferrite for Advanced Millimeter‐Wave Absorption

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The growing deployment of high‐frequency electronic systems has intensified the demand for high‐performance microwave absorption materials. In this work, we developed La‐V co‐substituted barium hexaferrites, Ba1‐xLaxFe11.9V0.1O19 (BLFVO), via a sol‐gel route.

Qualitative Evaluation of the Magnetocrystalline Anisotropy in Spinel Ferrite Nanoparticles Using Polarized Neutron Powder Diffraction

Small, Volume 22, Issue 35, 23 June 2026.
Polarized neutron powder diffraction is used to qualitatively probe the magnetocrystalline anisotropy of cobalt‐doped ferrite nanoparticles. The analysis of local magnetic susceptibility tensors and magnetization ellipsoids reveals how cobalt incorporation modifies both the magnitude and orientation of anisotropy, providing a new approach to compare ...

Quantitative Determination of Iron Redox State in Copper–Iron–Silicate Slags by Electron Probe Microanalysis

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
The manuscript presents a quantitative approach for determining iron oxidation state in multicomponent silicate oxide systems through direct oxygen measurement by EPMA. The study provides experimentally validated data obtained under controlled equilibrium conditions. The methodology is intended to offer a broadly applicable framework for studying redox

Low temperatures and high water/rock ratios in asteroid (101955) Bennu's history based on X‐ray powder diffraction of returned samples

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1077-1094, June 2026.
Abstract Samples returned by NASA's OSIRIS‐REx mission from the carbonaceous asteroid (101955) Bennu hold clues about conditions in the early solar system and the formation of planetary bodies. Initial investigation of Bennu samples found that they are rich in phyllosilicates and other secondary minerals formed during aqueous alteration of a larger ...

Thermal decomposition of illite

Materials Research, 2004
The effect of heat treatment on illite in air at temperatures ranging from 750 to 1150 °C was studied using the Mössbauer effect in 57Fe. The dependence of the Mössbauer parameters and relative percentage of the radiation absorption area was measured as ...

New Heptacoordinated Organotin(IV) Complexes Derivatives of 2,6-diacetylpyridinebis(2-furanoylhydrazone), H2dapf, and 2,6-diacetylpyridinebis(2-thenoylhydrazone), H2dapt: Crystal and Molecular Structure of [Me2Sn(Hdapt]Br.H2O

Journal of the Brazilian Chemical Society, 1999
The reaction of the ligands H2dapf and H2dapt, with R4-mSnXm (m = 2, 3; R = Me, Ph and X = Cl, Br) led to the formation of eight new heptacoordinated organotin(IV) complexes, which were studied by microanalysis, IR, NMR and Mössbauer spectroscopy to ...
