来源：ACS Publications Designing functional materials is a promising route to enhance modern technologies. Here, an unreported hexagonal perovskite, LuGaO3, is successfully synthesized in thin-film form, and its structure is characterized and compared to isostructural LuFeO3, along with solid solutions of the two (LuFexGa1–xO3, for x = 0.25–0.75). The addition of gallium was found to degrade the structural quality of LuFeO3, rendering the hexagonal phase nearly unobservable in pure LuGaO3. Extensive growth experiments (and thermodynamic phase diagrams for related systems) suggest a tendency for L...

Compensation-Like Temperature and Spin-Flip Switch in Strained Thulium Iron Garnet Thin Films: Tuning Sublattice Interactions for Ferrimagnetic Spintronics 来源：ACS PublicationsCertain rare-earth iron garnet (RIG) thin films combine desirable properties such as low magnetic damping, high magnetostriction, and, in some cases, perpendicular magnetic anisotropy (PMA), making them attractive for spintronics applications. However, the interplay between their magnetic sublattices in confined films remains poorly explored, particularly the coupling between 3d and 4f electrons. Here, we investigate...

Computational Investigations of Metal–Metal Bonding in Molecular Thorium Compounds and Ce and Group IV Analogues来源：ACS PublicationsWe report quantum chemical investigations of metal–metal bonding in molecular thorium clusters and compare them with cerium and group IV transition metal analogues. We explore periodic trends in metal–metal bonding and the roles of electron delocalization, orbital diffuseness, and oxidation state. As cluster size increases in the series [{Th(η8-COT)Cl2}nK2] (COT = C8H8, n = 2–5, 2–5) and [Th4Cl4(η8-COT)4]2+ (T), n-center-2-electron bonding weakens. Quantum theory o...

来源：ACS PublicationsThe reaction between isophthalic acid (H2L1) and Gd(NO3)3·6H2O leads to the formation of a two-dimensional (2D) extended framework with the molecular formula [Gd2(L1)3(H2O)2]n (1). Complex 1 crystallizes in monoclinic space group P21/n. The compound undergoes a reversible crystalline-to-amorphous phase transition. Magnetic susceptibility measurements on a polycrystalline sample of 1 reveal a weak ferromagnetic interaction between the Gd(III) centers below 20 K. Analysis of the magnetic data using the Fisher chain model indicates an exchange interaction strength (J) of +...
