Ranges of the allowed projections of the total magnetic moment and the vector of antiferromagnetism on the anisotropy axis for ideal () and “uncompensated” () antiferromagnetic particles (see main text). Dashed lines , , and correspond to the normal uniform precession modes of magnetizations of sublattices and .
