In this report, we present combined experimental and theoretical studies of the trinuclear {[L2Co2Tb][NO3]} (LH 3 = (S)P[N(Me)Nî -CH -C6H3-2-OH-3-OMe] 3) complex exhibiting single molecule magnet properties. Our theoretical model includes the axial crystal fields acting on the Tb III and CoII ions, the spin-orbit interaction operating within the 4T1 ground term of the CoII ion, and the ferromagnetic exchange between Tb and Co magnetic centers. We demonstrate for the [L2Co2Tb]+ complex that the strong negative single-ion anisotropy of both TbIII and CoII ions is the reason for the observed slow relaxation of magnetization. The elaborated model describes perfectly the experimental magnetic properties of the complex as a function of temperature and the external magnetic field. |
