  • Molecular magnets may provide fundamental building blocks for future spintronic and quantum information technologies. Here, the authors demonstrate how the Yb4 tetrahedral components of inorganic materials Ba3Yb2Zn5O11behave as isolated molecular magnets.

  • Magnetocaloric materials are used in adiabatic demagnetization refrigerators to reach extremely low temperature without using Helium. Here, the authors report a large magnetocaloric effect in YbPt2Sn, and show how the properties of this alloy makes it a good magnetocaloric material.

  • A thermodynamic study of doped single crystals of NbFe2 reveals the phase diagram of this system as a function of temperature, magnetic field and Nb doping — which includes an unusual quantum tricritical point.

  • The heavy-fermion compound YbRh2Si2 possesses a quantum critical point, at which the standard theory of electron behaviour in metals is expected to break down; such anomalous behaviour has now been observed.

  • The nature of quantum criticality in intermetallic f-electron compounds exhibiting valence fluctuations is not well understood. Here, using a combination of experimental techniques, the authors attribute quantum criticality in YbAlB4 to the anisotropic hybridization between the conduction and f-electrons.

  • An experimental study of the rare-earth intermetallic system LuPt2In reveals a strong enhancement of superconductivity near the charge density wave quantum critical point. This represents an unusual counter-example to cuprates, in which superconductivity and charge density waves tend to compete.

  • 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, YbNi1.6Sn is identified as a metallic magnetocaloric which retains high entropy into the 100 mK regime, providing an economical and durable alternative to magnetic refrigeration.
