Manifold relaxation processes in a mononuclear Co(II) single-molecule magnet

Mononuclear complex [Co(Me6tren)Cl]ClO4 shows the slow magnetic relaxation in an applied external field BDC = 0, 0.2, 0.4, and 0.8. The effective barrier to spin reversal stays approximately U/kB ∼ 20 K. The extrapolated relaxation time for the faster relaxation process varies between 3 × 10−9 and 6 × 10−8 s.216
