Effect of Fe Doping on the Structural, Morphological, Optical, and Magnetic Properties of Ca2InTaO6 Double Perovskite

physica status solidi (b), EarlyView.
Fe‐doped Ca2InTaO6 double perovskites are synthesized via solid‐state reaction and systematically investigated. Rietveld refinement confirms orthorhombic Pbnm structure, while optical studies reveal a bandgap narrowing from 3.31 to 2.84 eV. Photoluminescence spectra exhibit strong red emission at 671 nm with optimal intensity at 10 mol% Fe ...

Structural and Transport Properties of Thick and Thin Cr2AlC Films

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
This study compares structural and transport properties of Cr2AlC thin films (50 and 500 nm) systematically disordered by ion irradiation. Columnar grain growth is observed only in 500 nm films, while both films exhibit a weak fiber texture. Kondo scattering from displaced Cr atoms leads to a resistivity upturn, with distinct magnetoresistance in each ...

Room Temperature Evidence of PtTe2 Topological Semimetal Character

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
We report on a melt growth process for the synthesis of high‐quality PtTe2 crystals, as assessed by X‐ray diffraction and X‐ray photoemission spectroscopy characterization. By angle‐resolved photoemission spectroscopy investigation, we observe the expected topological features at cryogenic temperature and we demonstrate their stability even at room ...

Non-conventional resonant behavior of an unconfined magnetic domain wall in a permalloy strip

APL Materials
The resonant dynamic of a magnetic domain wall in a permalloy microstrip has been investigated using an innovative experimental setup that enables a simultaneous measurement of the ferromagnetic resonance and the magnetoresistance.

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, EarlyView.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

Small, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

System Design Considerations for Magneto‐Electrocatalysis of the Oxygen Evolution Reaction

Small, EarlyView.
Electrocatalytic water‐splitting can be controlled using a magnetic field. The commercial prospects are exciting, but the progress is stuck in the fundamental stage of research. Progress is stagnated by publications with conflicting results, incomplete analysis, and inconsistent experimental setups.

Vertical spin valve performance of NiFe/Co-PANI/NiFe system

St. Petersburg Polytechnical University Journal: Physics and Mathematics
The organic materials are found to be potent candidates for spintronics applications. Here, we have presented a cobalt-loaded polyaniline (Co-PANI)-based spin valve with NiFe alloy as ferromagnetic contacts.

Tunable Colloidal Synthesis Enabling μ‐ARPES on Individual Bismuth Nanocrystals

Small, EarlyView.
We report a highly controlled colloidal synthesis of Bi nanosheets with tunable lateral sizes (0.6–4.1 µm), hexagonal shape, and a layered single‐crystalline structure along the {00l} planes. The nanosheets feature high phase purity and excellent ambient stability. Remarkably, O2 promotes larger lateral growth with ultra‐smooth surfaces. This scalable,

Separation of Magnetic Microparticles With Different Molecular Surface Functionalizations by Close‐to‐Surface Traveling‐Wave Magnetophoresis

Small, EarlyView.
Inducing surface‐near magnetic particle transport inside a static liquid via an engineered, dynamic potential energy landscape, different chemical surface properties of otherwise identical particles can be distinguished using simple optical observation.
