ScholarBank@NUS Repository. https://doi.org/10.1002/anie.201201478 | Abstract: | Two ways to relax: A defect-dicubane Co 2Dy 2 single-molecule magnet (SMM) displays slow relaxation of magnetization with a blocking temperature of 22 K (at 1500 Hz), the highest reported for a 3d-4f-based SMM. Analysis of the relaxation reveals two distinct blocking regimes, one of which is intraionic, localized on the Dy III ions, while the other is exchange-based.
