Carpenter, Miguel B. Costa, Guillaume F. Nataf, and Xavier Moya Phys. Rev. Materials 7, 083601 (2023) – Published 11 August 2023 The properties of materials that lay the groundwork for greenhouse gas-free solid-state cooling are intricately tied to their proximity to a phase transition—a phenomenon that unfolds reversibly in response to an externally applied field. Enter ammonium sulfate, a material that holds the promise of effectiveness and affordability within this remarkable realm. Its allure stems from a structural phase transition occurring at 225 K, which can be driven by changing hydrostatic pressure and electric fields. However, because of a large change in volume, cycling crystals through the transition typically results in mechanical failure. In this work, resonant ultrasound spectroscopy reveals the strain relaxation mechanisms responsible for this failure and a thermal pathway by which it can be avoided.     Editors' Suggestion Effect of Pt vacancies on magnetotransport of Weyl semimetal candidate GdPtSb epitaxial films Dongxue Du, Laxman Raju Thoutam, Konrad T. Genser, Chenyu Zhang, Karin M. Rabe, Tamalika Samanta, Taehwan Jung, Bharat Jalan, Paul M. Voyles, and Jason K. Kawasaki Phys. Rev. Materials 7, 084204 (2023) – Published 25 August 2023 Bismuth-containing half-Heusler compounds were among the first identified Weyl semimetals. However, it remains a question whether other half-Heuslers also exhibit Weyl physics. Additionally, the impacts of point defects on the transport properties of Weyl semimetals are often overlooked. One experimental signature of Weyl nodes is the chiral anomaly, which involves charge pumping between Weyl nodes in reciprocal space. In this study, the authors demonstrate that naturally occurring Pt vacancies in GdPtxSb epitaxial films complicate the identification of the chiral anomaly through magnetotransport measurements. On the other hand, they observe signatures of the topological Hall effect, indicating the presence of chiral spin textures in real space.     Editors' Suggestion Structural and optoelectronic properties of thin film LaWN3 Rebecca W. Smaha, John S. Mangum, Ian A. Leahy, Julian Calder, Matthew P. Hautzinger, Christopher P. Muzzillo, Craig L. Perkins, Kevin R. Talley, Serena Eley, Prashun Gorai, Sage R. Bauers, and Andriy Zakutayev Phys. Rev. Materials 7, 084411 (2023) – Published 23 August 2023 Perovskite and related materials exhibit a staggering array of interesting ground states and functional applications. Among these, nitride perovskites are predicted to possess intriguing physical properties, but they remain underexplored due to the challenges in synthesizing materials without unintentional oxygen incorporation. LaWN3, recently identified as the first fully nitrided perovskite, displays polar symmetry and a large piezoelectric coefficient. However, its predicted polarization switching (common for ferroelectrics) is hindered by a significant leakage current, necessitating a better understanding of its electronic structure and optical properties. This study delves into the structure and optoelectronic properties of thin film LaWN3 in greater detail, employing combinatorial techniques to establish correlations between properties and cation stoichiometry.     Editors' Suggestion Letter Correlated anharmonicity and dynamic disorder control carrier transport in halide perovskites Maximilian J. Schilcher, David J. Abramovitch, Matthew Z. Mayers, Liang Z. Tan, David R. Reichman, and David A. Egger Phys. Rev. Materials 7, L081601 (2023) – Published 23 August 2023 Charge transport characteristics in optoelectronic devices play a crucial role in their efficiency. Research over the past decades has established strategies to alter charge transport behavior through material design. However, when atomic motion becomes complex at elevated, application-relevant temperatures, the established structure-property relations are less predictive. In this work, the authors take a major step to solve this critical problem by quantitatively connecting vibrational anharmonicity and dynamic disorder in model anharmonic semiconductors. It is reported that the materials' correlated behavior determine carrier mobilities and their temperature dependencies in halide perovskites, establishing these phenomena as knobs to tune key optoelectronic properties of important optoelectronic materials.     LETTERS Crystal growth, crystallization, and kinetics Letter Crystal to crystal transformation in soft ionic microgels: Kinetics and the role of local mechanical susceptibilities Saswati Ganguly, Sofi Nöjd, Anand Yethiraj, Peter Schurtenberger, and Priti S.
