A square antiprism dysprosium single-ion magnet with an energy barrier over 900 K

Herein we report a stable and high-performance Dy( iii ) single-ion magnet (SIM) showing an energy barrier of 944 K under zero dc field, with an open hysteresis loop up to 6 K. To the best of our knowledge, this is the highest energy barrier for a square antiprism as well as phosphine oxide based Dy...

Summary:Herein we report a stable and high-performance Dy( iii ) single-ion magnet (SIM) showing an energy barrier of 944 K under zero dc field, with an open hysteresis loop up to 6 K. To the best of our knowledge, this is the highest energy barrier for a square antiprism as well as phosphine oxide based Dy-SIMs, reported so far. A stable and high-performance molecule displays a reversal barrier >900 K, which is the highest among square antiprismatic dysprosium single-ion magnets.
