Anomalous lattice expansion of bcc Ta in helium-loaded diamond anvil cells

Guoyin Shen, Jesse S. Smith, Scott D. Ambos, D. F. Smith et autres

Anomalous lattice expansion of bcc Ta is observed in helium-loaded diamond anvil cell (DAC) experiments near 6 GPa and above 400 K, while co-loaded W, Mo, and Au exhibit normal thermal expansion. The Ta volume expansion increases with temperature, reaching ∼13% near …

High‐Pressure Synthesis of a Novel Body‐Centered Tetragonal Vanadium Carbide

Elizabeth E. Cote, Tracey L. Nelson, Scott D. Ambos, John Arigbede et autres

ABSTRACT High‐pressure synthesis is a powerful tool for the discovery of new phases, and can be used to uncover new metastable phases even within well‐explored systems. The vanadium–carbon system is one of the most well‐studied binary systems due to its importance in …

Fragmenting the Kagomé Lattice: Pressure-Tuned Anisotropy of Cu2+ Triangles in a Novel Atacamite Relative CaCu(OH)3Cl

Scott D. Ambos, Nicholas S. Manganaro, Matthew DeCapua, Dongzhou Zhang et autres

The atacamite family of copper halide minerals contains several prominent quantum spin liquid candidate materials, chiefly herbertsmithite. Unfortunately, an intrinsic chemical disorder in herbertsmithite complicates attempts to perform magneto-structural correlations that deconvolute the fundamental magnetic exchange terms that underpin frustration. We sought …

High-Pressure Polymorphism in Silver Ferrite Delafossite, AgFeO2

Nicholas S. Manganaro, Scott D. Ambos, Matthew DeCapua, Scott D. Thiel et autres

The delafossites are a class of layered metal oxides that are notable for being able to exhibit optical transparency alongside an in-plane electrical conductivity, making them promising platforms for the development of transparent conductive oxides. Pressure-induced polymorphism offers a direct method for …
