Ferrimagnetic interaction

Ferrimagnetic interaction

A ferrimagnetic interaction is a specific type of antiferromagnetic interaction in which the net spin of the system is not equal to zero due to the spin in each direction not being equal, and therefore not cancelling. A classic example is a dodecanuclear Manganese molecule with an effective spin of S = 10 derived from antiferromagnetic interaction on Mn(IV) metal centres with Mn(III) and Mn(II) metal centres. [R. Sessoli, D. Gatteschi, G. Christou, N. Hendrickson "et al", J. Am. Chem. Soc., 1993, "115", 1804]
