Ei. Gotovenchits et al., ORBITAL GLASS STATE IN QUASI-2-DIMENSIONA L HEISENBERG-ANTIFERROMAGNET EU2CUO4, Fizika nizkih temperatur, 22(11), 1996, pp. 1333-1336
The orbital glass state, induced by 2D Heisenberg antiferromagnetic sp
in fluctuations with large correlation radii, is studied. Such an orbi
tal glass possesses a lot of specific properties along with traditiona
l ones typical of spin glasses. The properties of the orbital glass ar
e supposed to be due to the self-consistent interaction between spin a
nd orbital subsystens of the crystal.
