Magnetic excitations in molecular magnets with complex bridges: The tetrahedral molecule Ni$_4$Mo$_{12}$

30 Aug 2019 M. Georgiev H. Chamati

We investigate the spectroscopic magnetic excitations in molecular magnets with complex intermediate structure among the magnetic ions. Our approach consists in introducing a modified spin Hamiltonian that allows for discrete coupling parameters accounting for all energetically favorable spatial distributions of the valence electrons along the exchange bridges connecting the constituent magnetic ions...
