Quasi-one-dimensional nature of magnetic ordering due to the cooperative Jahh-Teller effect in the garnet NaCa2 Cu2V3O12 (CuVG)
Kazei Z. A., Novak P., Sokolov V. I.
Based on the results of measurements of the magnetic properties and heat capacity of CuVG, it is concluded that quasi-one-dimensional antiferromagnetic ordering, whose microscopic mechanism is related to antiferrodistortional ordering of the orbitals of Cu ions as a result of the cooperative Jahn-Teller effect (CJTE), arises in this compound at T~ 10 K.
