11. The following equation is used for the theoretical fitting: {Mathematical expression} where N is the Avogadro's number, β is the Bohr magneton, k is the Boltzmann constant, g is an average g factor and taken here to 2.0, J is the exchange coupling between radical and Mn spins and J′ is that between two radicals, which is neglected in this case. Cf. Gruber S.J., Harris C.H., and Sinn E. J. Chem. Phys. 49 (1968) 2183 The reason for the deviation of the fitting data around low temperature region from the experimental ones is thought to be due to intermolecular antiferromagnetic interactions between the spin centers.
