  • Large barocaloric effects driven by pressure may lead to environmentally friendly cooling, but they have only been observed in a small number of relatively expensive magnetic materials. Here, the authors show large barocaloric effects near the ferrielectric phase transition in ammonium sulphate.

  • The oxidation state of hydride ions in oxide hosts is a matter of debate. Here, the authors address this question with a range of techniques and suggest that the electron density near an incorporated hydride ion is less than that at the hydrogen in a hydroxide ion, contrary to formal valence arguments.

  • Kagome metals house a range of competing ground states leading to superconducting as well as topological features and so there has been significant recent interest in their underlying physics. Here, the authors use muon-spin rotation to identify slow fluctuations and low-temperature volume-wise magnetic evolution of the static c-axis ferrimagnetic patches in TbMn6Sn6, which seems to be intimately coupled to its topological electronic properties.

  • The study focuses on the charge order in LaRu3Si2, a material with a kagome lattice structure, discovering a charge-ordered state that persists at or above room temperature. This finding classifies LaRu3Si2 as the kagome superconductor with the highest charge ordering temperature, suggesting potential for applications in devices operating at normal environmental conditions without the need for cooling.
