Abstract:

A rigorous theory is given of the ground state of an antiferromagnetically-coupled spin impurity s 12 in a ferromagnetic host of arbitrary S. This is compared with the results of spin wave theory, providing some insight into the corresponding calculation for a pure antiferromagnet. Author
