Abstract

Coupled electron-nuclear oscillations in antiferromagnetics with anisotropy of "light plane" type in the strong external magnetic field are under consideration. The new mode \epsilon_{2k} of these coupled oscillations is obtained for antiferromagnetic systems by using "u-v"-Bogolubov?s unitary transformations. The dynamic shift of the frequency of nuclear magnetic resonance concerned with this mode is obtained.
