Key points
- Dysprosium metallocene compound shows magnetic hysteresis up to 80 K.
- This temperature is significantly higher than the typical liquid helium requirement for SMMs.
- Ligand tuning was the key mechanism for achieving higher operating temperatures.
- The findings suggest a pathway for developing SMMs that operate at even higher temperatures.

Abstract
Breaking through the nitrogen ceiling Single-molecule magnets could prove useful in miniaturizing a wide variety of devices. However, their application has been severely hindered by the need to cool them to extremely low temperature using liquid helium. Guo et al. now report a dysprosium compound that manifests magnetic hysteresis at temperatures up to 80 kelvin. The principles applied to tuning the ligands in this complex could point the way toward future architectures with even higher temperature performance. Science , this issue p. 1400
