Electron paramagnetic resonance (EPR) of a new compound {[Nd2(α-C4H3OCOO)6(H2O)2]}n composed of Nd3+-Nd3+ dimers is reported. The anisotropy parameters of the spin-spin interaction are determined by fitting experimental and simulated spectra in X- and Q-bands. It is shown that the anisotropy of the exchange interaction gives the main contribution to the anisotropy of the spin-spin interaction. The observed anisotropy disagrees with the expected in the model of the isotropic exchange interaction between real spins. A feature of the EPR spectrum not described by the model of the isolated Nd-Nd dimers and reflecting the magnetization transfer between dimers is detected. The magnetization transfer due to both the relaxation transitions and the interdimer interaction is considered. |
