  Metallic local-moment magnetocalorics as a route to cryogenic refrigeration

  Commercial adiabatic demagnetisation refrigerators are typically based on hydrated salts that are subject to corrosion and have poor thermal conductivity and low entropy at sub-Kelvin temperatures. Here, YbNi_1.6Sn is identified as a metallic magnetocaloric which retains high entropy into the 100 mK regime, providing an economical and durable alternative to magnetic refrigeration.

  Orthogonal antiferromagnetism to canted ferromagnetism in CaCo₃Ti₄O₁₂ quadruple perovskite driven by underlying kagome lattices

  Quadruple perovskites are characterized by competing long-range spin interactions that result in complex magnetic structures. Here, the authors synthesize and characterize the magnetic behaviour of CaCo₃Ti₄O₁₂, suggesting that the observed magnetic structures arise from different ways to avoid frustration in underlying kagome lattices.

  Shaping and silane coating of a diamine-grafted metal-organic framework for improved CO₂ capture

  Metal organic frameworks (MOFs) are promising for CO₂ capture. Here, the Mg₂(dobpdc) MOF is synthesized as micron-sized beads with a silane coating resulting in > 11 wt% CO₂ absorption, which is retained after three days in a humid environment at 140 °C.

  Stabilization of a honeycomb lattice of IrO₆ octahedra by formation of ilmenite-type superlattices in MnTiO₃

  Atomically thin films are ideal candidate materials for realizing clean, long sought-after, Kitaev spin liquids. Here, a two-dimensional IrO₆ honeycomb lattice is stabilized within a MnTiO₃ ilmenite superlattice, inducing a suppression of antiferromagnetic order that suggests potential spin-liquid behavior.
