Singlet ground state magnets still attract much attention. In these systems magnetic ordering occurs via the polarization of the ground state, and noticeable dispersion of well defined excitations is expected in systems where the exchange coupling is about equal to the crystal field energy. In addition, the two singlet-triplet systems PrSbl and TbP2 where single crystals are available and which have been studied in detail showed a pronounced splitting of the Г1–Г4 magnetic excitations where the triple degeneracy was lifted along [100] and [011] by a strong anisotropy of the exchange.
