This is by far the largest Ueff barrier for any chlorido-bridged lanthanide single-molecule magnet. We observe two relaxation processes with near-identical temperature dependencies, one of which disappears upon magnetic dilution. We suspect that these two processes are the isolated and coupled relaxation processes.4enA dichlorido-bridged dinuclear Dy(III) single-molecule magnet with an effective energy barrier larger than 600 K2019-06-1210.1039/C9CC02436K85068579849
