Zeeman levels of a trimeric cluster are obtained in the frameworks of a model, accounting for both the isotropic exchange and antisymmetric Dzyaloshinski-Moriya interactions. The field and angular dependences of the radio-frequency E.P.R.-transitions

The ESR spectra of polycrystalline samples of Zn4O[(CH3)2CHCOO]6 and Zn4O[(CH3)3CCOO]6, activated by Mn2+ ions at various concentrations, were investigated. An analytical theory was developed for the contour of the hyperfine components of the permitt

A many-electron theory is proposed for exchange and tunneling levels of dimeric mixed-valence clusters. Transition-metal ions are examined, and it is established that the parameters of the Heisenberg and double-exchange interactions depend on the con

The Mossbauer spectra of tetrameric antiferromagnetic clusters possessing spin-coupled orbitally degenerate ground states are considered. The orbital degeneracy of the electronic exchange sub-system leads to the origin of hybrid electron-nuclear stat

The theory of double exchange is generalized to mixed valence (MV) trinuclear clusters. The results obtained by quantum-theoretical calculations of exchange and resonance splittings are compared to the results of the model theory which takes account

Electron-nuclear quadrupole interaction in trimeric antiferromagnetic clusters with half-integer ion spins is considered. The electronic shell of the exchange cluster is shown to produce electric field gradient at the nuclei. The antisymmetric exchan

A theory of the vibronic reduction of the energy levels of transition metal mixed valence clusters is developed. The 2T2(t2) - 3T1(t)-type system is considered in detail. The vibronic model takes into account the interaction with the totally symmetri
