Origin of the low thermal conductivity and thermal properties of BaIn2Te4

Materials research involving multinary chalcogenide compositions for technologically significant applications continues to attract attention, and an understanding of the thermal properties of materials is essential for all technologically significant applications. Herein we repor...

Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields

ABSTRACT Controlling terahertz (THz) waves is important for next‐generation communications, sensing, and imaging technologies. However, it is still unclear precisely how THz signals can be manipulated by various materials. Herein, we report the design and synthesis of four coordi...

Kinetic Control of Rare Earth Element Separation via Interfacial Solvent Extraction and Low-Gradient Magnetic Fields

Abstract The production of energy-efficient technologies and advanced electronics requires high-purity critical minerals, such as individually separated rare earth elements (REEs). Chemical REE separation processes rely on small differences in physicochemical properties (i.e., io...

Electrically controllable superconducting memory effect in UTe2

Abstract Multiphase superconductors—materials that host two or more distinct superconductive phases—are exceptionally rare. Examples include heavy-fermion CeRh 2 As 2 alongside some uranium compounds such as UPt 3 and URhGe (refs. 1,2,3 ). In the multiphase p -wave superfluid 3 H...

Coherent Pulsed Dynamic Nuclear Polarization with Endogenous Metal Ions

Abstract Dynamic nuclear polarization (DNP) can overcome the intrinsically low sensitivity of nuclear magnetic resonance (NMR) and enable structural characterization of a wide range of materials. In inorganic solids, DNP can be achieved endogenously by introducing paramagnetic me...

3D bulk-resolved g-wave altermagnetic order parameter in CrSb

Abstract Electronic phases of matter, such as magnetism and superconductivity, are defined and distinguished by their order parameters quantifying the spontaneous symmetry breaking underlying each phase. Simple cases include the uniform magnetization of ferromagnets 1,2 and the i...

Tunable Polariton Canalization in Natural Van Der Waals Oxide

ABSTRACT Hyperbolic phonon polaritons (HPPs) are coupled oscillations of anisotropic lattice vibrations and electromagnetic fields that confine the latter to the nanoscale, enabling novel nano‐polaritonic devices. While HPPs have been identified in multiple layered materials, ach...

Flux-Driven Order–Disorder Polymorphs of KagomeSmFe6Ge6

Abstract While polymorphism in kagome-derived intermetallics offers a powerful route to controlling structure–property relationships, it still remains poorly explored for many rare-earth members due to synthetic constraints. Here, we report the discovery and controlled growth of...
