摘要：
For the first time the exchange interaction between copper and non-Kramers Tb(3+)ions was studied by means of electron paramagnetic resonance (EPR). Features of the manifestation of this interaction in the EPR spectra of dimer fragments Cu-Tb and pentanuclear fragments Cu-Tb-Cu-Tb-Cu are analyzed. The possibility to determine the sign and value of this interaction from EPR spectra for the case when the lowest states of Tb3+ are the states vertical bar 0 > vertical bar +/- 1 > is shown. The exchange interaction between copper and trivalent terbium ions in the studied pentanuclear complex is ferromagnetic.
