Magnetron Sputtering Synthesis of La‐Doped BiFeO3 Thin Films and Enhanced Exchange Bias in CoFeB/Bi1‐xLaxFeO3 Heterostructures

Advanced Physics Research, EarlyView.
This study explores the epitaxial growth of high‐quality La‐doped BiFeO3 (BLFO) thin films at 550 °C using magnetron sputtering. The films exhibit good ferroelectric properties and low leakage current. A BLFO/CoFeB heterostructure is constructed, achieving an exchange bias field exceeding the coercive field at room temperature.

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency

Advanced Physics Research, EarlyView.
Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Supercritical Carbon Dioxide‐Assisted Interface Formation of LaAlO3/SrTiO3 for Room‐Temperature Ferromagnetism

Advanced Physics Research, EarlyView.
This work pioneers a non‐invasive route for strain engineering of quantum states at complex oxide interfaces, making use of supercritical CO2 as a tunable “strain field” to induce room‐temperature ferromagnetism in 3D LaAlO3/SrTiO3 composites. Structural and chemical analyses confirm the magnetism is strictly interfacial and driven by lattice tensile ...

Photocatalytic Oxygen Evolution with Prussian Blue Coated ZnO Origami Core‐Shell Nanostructures

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Prussian Blue and its derivative hold significant potential for photocatalytic oxygen evolution. IN this contribution the photocatalytic oxygen evolution reaction (OER) was characterized using a hybrid catalyst consisting of Prussian Blue coated ZnO nanostructures. The resulting heterojunction, which was characterized both structurally and functionally,

Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.
