Introduction to Molecular Magnetism
... What is the origin of the slow relaxation of the magnetization? • The large S ground state has 2S+1 spin microstates, which correspond to the MS states in the absence of transverse anisotropy. • These can be split up in zero field by spin-orbit coupling or magnetodipolar interactions if S>½. This i ...
