Effects of chemically induced contraction of a coordination polyhedron on the dynamical magnetism of bis(phthalocyaninato)disprosium, a single-4f-ionic single-molecule magnet with a Kramers ground state.

摘要: Chemically induced longitudinal contraction of the square-antiprism coordination polyhedron a peripherically substituted bis(phthalocyaninato)dysprosiumate(III), dysprosium-based single-4f-ionic single-molecule magnet having Jz = ±13/2 Kramers doublet ground state, resulted in drastic changes dynamical magnetism including doubling energy barrier, 2-order-of-magnitude decrease spin reversal rate, significant rise blocking temperature, and first observation emergence large remanent magnetization.
