抄録

Magnetic interactions in the nanoscale ferrimagnetic ring [Mn(hfac)₂NITPh]₆ abbreviated as Mn₆R₆ are estimated by comparing experimental data with our numerical data as obtained from the exact diagonalization of a Heisenberg model. Our results suggest that next nearest neighbor radical–radical interactions are essential to reproduce the magnetic structure of Mn₆R₆ well. The existence of these interactions means that Mn₆R₆ is a kind of frustrated spin cluster. We predict that the field derivative of magnetization should have two peaks in the range of magnetic field 380–420 T, which is beyond the range of current experimental observations. We also find that the local spin density of the frustrated model shows a different behavior from those of non-frustrated models studied in preceding works.
