Abstract:
The excitation spectrum of a catena-[Fe$^{\text{II}}$(ClO$_4)_2\{$Fe$^{\text{III}}(\text{bpca})_2
\}]$ClO$_4$ anisotropic 1D magnet with alternating high-spin and low-spin iron ions has been calculated with the use of the diagrammatic technique for Hubbard operators. This has allowed establishing conformity with the Ising model, for which the magnetic susceptibility has been calculated by the transfer-matrix method. The introduction of a statistical ensemble taking into account the presence of chains with different lengths and iron ions with different spins has allowed describing the modification of the magnetic susceptibility under optical irradiation.
