The Ni(II) complexes (Ni4Gd, Solv = MeOH; Ni4Dy, Solv = MeCN) are not SMMs in the absence of an applied dc field. The replacement of Ni(II) by Co(II) (Co4La, Solv = MeOH; Co4Gd, Solv = H2O; Co4Gd-MeCN, Solv = MeCN; Co4Tb, Solv = MeOH; Co4Dy, Solv = H2O) results in improved SMM properties.11 p.application/pdfeng(c) Rosado Piquer, Lidia et al., 2019Compostos metàl·licsPropietats magnètiquesMetallic compositesMagnetic propertiesinfo:eu-repo/semantics/article6911442019-09-06info:eu-repo/semantics/openAccess
