摘要：

The magnetic properties of a perfluorinated Er3+ complex, with record luminescent properties, have been investigated. [Er(F-TPIP)(3)] displays thermally activated slow relaxation of the magnetisation under an applied H-DC field of 500 Oe. The effective relaxation barrier E-eff is found to be 26.8 K (18.6 cm(-1)). At zero static field, efficient quantum tunnelling of the magnetization occurs. (C) 2015 Elsevier B.V. All rights reserved.
