Slow relaxation of the magnetization in two cobalt(iii)/cobalt(ii) dimers

“…7 A high ground spin state (S) and negative axial magnetic anisotropy (D) determines the value of this energy barrier (U = |D|S 2 and U = |D|(S 2 À 1/4) for the integer and half-integer spins, respectively). 8 The minimum temperature needed to overcome this energy barrier is called the blocking temperature, T B . If the thermal energy of the system is less than the value of the energy barrier (U), the magnetization is blocked.…”
