Research data for "Measurement of the quantum tunnelling gap in a dysprosocenium single-molecule magnet"

Magnetic data of [Dy(C5H2tBu3-1,2,4)2][B(C6F5)4] in the crystalline phase, and at various concentrations as dichloromethane (DCM) and difluourobenzene (DFB) frozen solutions. These data are magnetic field sweeps at varying rates, that show steps at zero magnetic field. These steps are due to quantum tunnelling of the magnetisation. The sweep rate dependence of the size of the step allows us to quantify the tunnelling gap, and hence assess this metric as a function of phase and concentration.

本数据集包含晶相下[Dy(C5H2tBu3-1,2,4)2][B(C6F5)4]（双(1,2,4-三叔丁基环戊二烯基)镝四(五氟苯基)硼酸盐），以及不同浓度的二氯甲烷（dichloromethane, DCM）、二氟苯（difluorobenzene, DFB）冷冻溶液的磁学数据。所有数据均为变扫场速率的磁场扫描曲线，其在零磁场处呈现台阶状特征。该台阶源于磁化量子隧穿（quantum tunnelling of the magnetisation）。通过台阶尺寸对扫场速率的依赖关系，可量化隧穿能隙（tunnelling gap），进而基于物相和浓度对该指标进行评估。
