在Au(111)表面完整地沉积了孤立分子Fe-14(BTA)(6)纳米磁体的亚单层分布，并用X射线磁性圆二色谱对其进行了研究。从磁化曲线中提取了磁化强度随外加磁场的变化规律，并在单分子水平上证明了高的磁热值。
A sub-monolayer distribution of isolated molecular Fe-14(bta)(6) nanomagnets is deposited intact on a Au(111) surface and investigated by X-ray magnetic circular dichroism spectroscopy. The entropy variation with respect to the applied magnetic field is extracted from the magnetization curves and evidences high magnetocaloric values at the single molecule level.
