A new magnetic relaxation phenomenon for an Ising dimer of a Tb-phthalocyaninato triple-decker SMM Tb-2(obPc)(3) (1) is reported. In Argand plots, the magnetic relaxation splits from a one-component system into a two-component system (temperature-independent and temperature-dependent regimes) in a dc magnetic field. There was clear evidence that the magnetic relaxation mechanisms for the Tb3+. dimer depended heavily on the temperature and the dc magnetic field. The relationships among the molecular structure. ligand field, ground state, and SMM properties in a direct current (dc) magnetic field are discussed. Furthermore, in order to investigate the stability of the complexes in vacuum evaporation (dry) process and the control of their surface morphology after transferring to a surface, we studied the lanthanoid-phthalocyaninato triple-decker molecule Y2PC3 deposited on a Au(1 1 1) surface using a low-temperature scanning tunneling microscope. It is important to both understand and control the quantum properties of Ln-Pc multiple-decker SMMs with an external field and the monolayer or multi-layer structures on a substrate for next generation devices, such as magnetic information storage.
