Magnetization steps in the molecular magnet NiMo revealed by complex exchange bridges
M. Georgiev, H. Chamati
We study the behavior of the magnetization and the magnetic susceptibility of molecular magnets with complex bridging structure. Our computations are based on a post-Hartree-Fock m…
Magnetic excitations in the trimeric compounds ACu(PO) (A = Ca, Sr, Pb)
M. Georgiev, H. Chamati
We study the magnetic excitations of the trimeric magnetic compounds ACu(PO) (A = Ca, Sr, Pb). The spectra are analyzed in terms of the Heisenberg model and a gener…
Magnetic Exchange in Spin Clusters
M. Georgiev, H. Chamati
We investigate the role of exchange bridges in molecular magnets. We explore their effects on the distribution of the valence electrons and their contribution to the exchange proce…
A systematic approach to determine the spectral characteristics of molecular magnets
M. Georgiev, H. Chamati
We devise a formalism to investigate in a systematic way the spectroscopic magnetic excitations in molecular magnets. This consists in introducing a bilinear spin Hamiltonian that…
