Terbium 82-84 mitochondrially encoded cytochrome c oxidase II Homo sapiens 199-205 23646986-12 2013 The energy barrier for the spin flipping was estimated from the Arrhenius plot to be 14.9(6) and 17.0(4) K for the Ni(II)-Tb(III) and Co(II)-Tb(III) complexes, respectively, under a dc bias field of 1000 Oe.
