The influence of an external magnetic field and magnetic-site dilution on the magnetization dynamics of a coordination network based on ferromagnetic coupled dinuclear dysprosium(III) units

摘要

We report the synthesis and magnetic properties of a mu(2)-OH- bridged dinuclear Dy(III) single-molecule magnet (SMM), [Dy-2(apca)(4)(mu(2)-OH)(2)(H2O)(2)](n) (Dy, Hapca = 3-aminopyrazine-2-carboxylic acid), which was assembled in a two-dimensional (2D) network. Magnetic studies reveal that Dy exhibits ferromagnetic interactions, multi-process slow relaxation of magnetization and hysteresis loops. The influence of an external magnetic field and magnetic-site dilution on the magnetic properties was also studied.
