Zero-Temperature Susceptibility of a Localized Spin Exchange
... It has been mentioned in the text that for the antiferromagnetic exchange, a non-realistic triplet bound state appears at and after the first approximation in the perturbation expansion, and this makes it difficult to treat the effect of the magnetic field comparable to the binding energy E. In this ...
