The susceptibility of a Kondo lattice has been theoretically examined. An instability condition against magnetic orderings gives an upper limit of the strength of attractive interactions due to RKKY exchange interactions in paramagnetic states; intrasite interactions causing the Kondo effect were in

## 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 gyr
In the present paper, we report the role of dipole-dipole interaction on the magnetic dynamics of single layer antiferromagnets. For this, the model Hamiltonian includes the exchange Heisenberg Hamiltonian as well as dipole-dipole interactions. Within the linear spin-wave theory, we employ the doubl
