Dy single-molecule magnets (SMMs), which have several potential uses in a variety of applications, such as quantum computing, were encapsulated in multi-walled carbon nanotubes (MWCNTs) by using a capillary method. Encapsulation was confirmed by using transmission electron microscopy (TEM). In alternating current magnetic measurements, the magnetic susceptibilities of the Dy acetylacetonato complexes showed clear frequency dependence even inside the MWCNTs, meaning that this hybrid can be used as magnetic materials in devices.
通过毛细管法将在诸如量子计算等各种应用中具有多种潜在用途的镝单分子磁体（SMMs）封装在多壁碳纳米管（MWCNTs）中。通过透射电子显微镜（TEM）确认了封装情况。在交流磁性测量中，即使在多壁碳纳米管内部，乙酰丙酮镝配合物的磁化率也表现出明显的频率依赖性，这意味着这种复合材料可作为器件中的磁性材料使用。
