Annotation

We presented detailed ESR linewidth investigations on CuTe2O5 single crystals. The anisotropic exchange interaction within the Cu alternating chain was successfully applied to describe its angular dependence. Hence from an ESR point of view, CuTe2O5 turns out to be alternating chain Cu(1)-Cu(2)-Cu?(1) and magnetic inequivalent Cu(3)-Cu(4)-Cu?(3) chain. Based on previous results on magnetic susceptibility in [3] and angular dependence ESR linewidth analyses, we believe that strongest isotropic exchange interaction is in 4 pair [Cu(2)-Cu?(1) or Cu(4)-Cu(3)] and equal J1a=93.3K and the second strongest value of exchange interaction in structural dimer (1 pair) is J1b=40.7K.
