Abstract
The replacement of coordinated acetylacetonate for nitrate around a Dy(III) ion results in the enhancement of the single molecule magnet properties of a {Co(III)2Dy(III)2} complex, resulting in a large thermal energy barrier and reduced quantum tunnelling at low temperatures. The analogous Tb(III) complex displays field induced SMM behaviour.
摘要
取代配合物中硝酸根配体为乙酰丙酮根配体，增强了一个{Co(III)2Dy(III)2}配合物的单分子磁体性能，导致在低温下具有较大的热能垒和减少的量子隧穿。类似的 Tb(III)配合物表现出场诱导的 SMM 行为。
