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.
在此，我们报道了一种稳定且高性能的Dy(III)单离子磁体（SIM），在零直流场下显示出944 K的能垒，在高达6 K时具有开放的磁滞回线。据我们所知，这是迄今为止报道的基于方形反棱柱以及氧化膦的Dy-SIMs中最高的能垒。
