Anionic and Magnetic Ordering in Rare Earth Tantalum Oxynitrides with an = 1 Ruddlesden-Popper Structure.

The new compounds RTaON with R = La, Ce, Nd, and Eu and 1.20 ≤ ≤ 2.81 have been obtained by a solid-state reaction between metal nitrides and oxides or oxynitrides under N gas at temperatures between 1200 and 1700 °C.

Prussian Blue Analogues as Positive Electrodes for Mg Batteries: Insights into Mg Intercalation.

Potassium manganese hexacianoferrate has been prepared by co-precipitation from manganese (II) chloride and potassium citrate, with chemical analysis yielding the formula K Mn[Fe(CN) ] □  ⋅ 1.1H O (KMnHCF). Its X-ray diffraction pattern is consistent with a monoclinic structure (space group P 2 /n, no.

High-Temperature Synthesis of Ferromagnetic EuTa(O,N) with a Triple Perovskite Structure.

Europium tantalum perovskite oxynitrides were prepared by a new high-temperature solid-state synthesis under N or N/H gas. The nitrogen stoichiometry was tuned from 0.63 to 1.

Spin-to-Charge Conversion in All-Oxide LaSrMnO/SrIrO Heterostructures.

Spin injection and spin-charge conversion processes in all-oxide LaSrMnO/SrIrO (LSMO/SIO) heterostructures with different SIO layer thickness and interfacial features have been studied. Ferromagnetic resonance (FMR) technique has been used to generate pure spin currents by spin pumping (SP) in ferromagnetic (FM) half-metallic LSMO. The change of the resonance linewidth in bare LSMO layers and LSMO/SIO heterostructures suggests a successful spin injection into the SIO layers.

Synchrotron radiation based characterization of battery materials.

Synchrotron radiation based techniques are powerful tools for battery research and allow probing a wide range of length scales, with different depth sensitivities and spatial/temporal resolutions. experiments enable characterization during functioning of the cell and are thus a precious tool to elucidate the reaction mechanisms taking place. In this perspective, the current state of the art for the most relevant techniques (scattering, spectroscopy, and imaging) is discussed together with the bottlenecks to address, either specific for application in the battery field or more generic.
