Atomic faulting drives exceptional toughness in low thermal expansion chromium alloys
Endowing functional properties with mechanical responses in traditional metals has been a frontier topic, akin to transforming base metal into gold. Chromium and its alloys, with their functional deficiencies and limited ductility, serve as typical examples. Herein, we report a Cr96Fe4Ge1.3B1 alloy that unifies low thermal expansion (LTE, αl = 1.79 × 10-6 K-1, 200 − 315 K)…

Dissecting Disorder: Defect-Driven Structural Complexity in Layered Li3InCl6 Solid Electrolyte
Halide solid electrolytes have emerged as promising candidates for solid-state batteries owing to their high oxidative stability and ionic conductivity. Among them, Li3InCl6 (LIC) has attracted significant attention. However, diffraction patterns of LIC synthesized via different methods exhibit distinct differences particularly at low-angle reflectionsindicative of underly…

Intrinsic topological Weyl phase transition induced by a magnetostructural transformation in a kagome magnet
Topological phase transitions provide a unique window into the interplay between structure, magnetism, and Weyl physics in magnetic Weyl semimetals. However, realizing an intrinsic Weyl phase transition between two distinct Weyl states near room temperature remains challenging. Here, we demonstrate that a magnetostructural transition effectively induces such a transition i…

Synergistic Doping and Stabilization of Magnetically Tunable LnTi3(Sb,Sn)4 (Ln: Ce–Gd) Kagome Metals
Here, we present our synthesis and characterization of the LnTi3(Sb,Sn)4 (Ln: Ce, Pr, Nd, Sm, Gd) family of cleavable kagome metals. While these materials are isostructural to the LnTi3Bi4 family, they only form as (Sb,Sn) solid-solutions with no corresponding LnTi3Sb4 or LnTi3Sn4 phases. We use a combination of first-principles density functional theory (DFT) and crystal…

Codimension-two spiral spin liquid in the effective honeycomb-lattice compound Cs3Fe2Cl9
A codimension-two spiral spin liquid is a correlated paramagnetic state with one-dimensional ground state degeneracy hosted within a three-dimensional lattice. Here, via neutron scattering experiments and numerical simulations, we establish the existence of a codimension-two spiral spin liquid in the effective honeycomb-lattice compound Cs3Fe2Cl9, which demonstrates an a…

Leveraging Polymorphism in YbCuBi to Map Transport and Elastic Properties
AMX Zintl compounds with the hexagonal ZrBeSi structure have gained significant attention for their remarkable vacancy tolerance and low thermal conductivity. Their 2D honeycomb sublattice, composed of M–X covalent bonds, is believed to contribute to high anharmonicity and unusual thermal transport properties. In this study, we explore the temperature-dependent polymorphis…

Collinear antiferromagnetic order in a quasi-two-dimensional triangular lattice compound DyNiAl4Ge2
The two-dimensional magnetic triangular lattice, with rare-earth local moments coupled through long-range interactions and hosting strong spin-orbit coupling, serves as an ideal platform for exploring novel quantum phenomena. Here, we report the physical properties of DyNiAl4Ge2 single crystals through comprehensive structural, magnetic, heat capacity, electrical transpor…

Pressure-induced cation and vacancy disorder-order transition and near-zero τf in deficient hexagonal perovskite Ba8ZnTa6O24 dielectrics
Pressure applications can enable the tuning of atomic/defect ordering and provide access to new functional materials. Here, we report that pressure-induced structural transformation featuring disorder-order transition of both cations and vacancies in the 8-layer deficient hexagonal perovskite tantalate dielectrics Ba8ZnTa6O24, which transformed the structure from twin to s…

Magnetic evolution induced by freezing of Ag+ fluctuations in an intercalated transition metal dichalcogenide
Here, we present a comprehensive study on the magnetic evolution processes in AgCrSe2 using both neutron scattering and theoretical calculations. The development of magnetic short-range correlation with decoupled interlayer interactions is confirmed between 55 and 200 K. Significant magneto-crystalline anisotropy energy around 0.1 meV of Cr3+ is identified that mainly cont…

Coexistence of ordered and disordered vacancies in tungsten diboride with a broken hexagonal symmetry
As an important member of transition-metal borides, tungsten diboride (i.e., WB2+𝑥) contains complex atomic vacancies with the originally assigned hexagonal symmetries, exhibiting many fascinating properties such as superconductivity and superior hardness. However, due to the difficulties in exploring atomic vacancies of transition-metal borides, the actual structure and c…

Structure and tunable temperature coefficient of magnetization of Mn4-xGaxC alloys prepared by induction melting method
The magnetization of most magnetic materials decreases monotonically with increasing temperature. In this work, we found that the temperature coefficient of magnetization of Mn4-xGaxC alloys can be tuned from negative values to positive values by controlling the composition x. The antiperovskite-type Mn4-xGaxC (0.05≤x≤0.75) alloys were prepared by using induction melting m…
