Structural and magnetic dimers in the spin-gapped system CuTe2O5 / J.Deisenhofer, R.M. Eremina, A. Pimenov, T. Gavrilova, H. Berger, M. Johnsson, P. Lemmens, H.-A. Krug von Nidda, A. Loidl, K.-S. Lee and M.-H. Whangbo // Physical Review B. – 2006. – Vol. 74. – pp. 174421-1 - 174421-8. |
| Аннотация |
We investigate the magnetic properties of the system CuTe2O5 by susceptibility and electron spin resonance
ESR measurements. The anisotropy of the effective g factors and the ESR linewidth indicates that the
anticipated structural dimer does not correspond to the singlet-forming magnetic dimer. Moreover, the spin
susceptibility of CuTe2O5 can only be described by taking into account interdimer interactions of the same
order of magnitude than the intradimer coupling. Analyzing the exchange couplings in the system we identify
the strongest magnetic coupling between two Cu ions to be mediated by a super-superexchange interaction via
a bridging Te ligand, while the superexchange coupling between the Cu ions of the structural dimer only results
in the second strongest coupling. |
