Abstract:

Single-molecule magnets(SMMs) continue to be an attractive research field because of their potential applications in quantum information storage and quantum computing. Lanthanide-based polynuclear system is an important avenue to explore in pursuit of SMMs with higher anisotropic barriers. The progress and prospect on pure 4f SMMs are briefly reviewed with an emphasis on the magnetic properties of the mono-, tri- and tetra-nuclear dysprosium SMMs.

Key words: Single-Molecule magnets, 4f ions, Slow relaxation of the magnetization, Quantum tunneling of magnetization, Magnetic characterization
