Abstract

The Ruderman‐Kittel‐Kasuya‐Yosida (RKKY) interaction has been extended to the case when an external magnetic field is taken into account. It has been shown that the RKKY Hamiltonian should contain the Zeeman‐like term in which the effective gyromagnetic factor occurs. This effective gyromagnetic factor contains a correction term which is linearly dependent on the contact potential between the localized spins and conduction electrons.

The Breit energy of a system, which is shown to depend on the external magnetic vector potential, is exactly transformed, by applying Gordon decompositions, to a form explicitly exhibiting some of the field dependence\_ The result is used to derive the leading Breit contributions to NMR chemical shi
