Neutron diffraction study of 1D quantum spin system Li$$_{2}$$ZrCuO$$_{4}$$ with incommensurate magnetic structure

Yasui, Yukio*; Igawa, Naoki   ; Kakurai, Kazuhisa

Magnetic structure has been studied by using neutron diffraction for quasi one-dimensional quantum spin system Li$$_{2}$$ZrCuO$$_{4}$$ with CuO$$_{2}$$ ribbon chains. The CuO$$_{2}$$ ribbon system Li$$_{2}$$ZrCuO$$_{4}$$ exhibits the antiferromagnetic transition at T$$_{N}$$ $$sim$$ 7 K, however, the magnetic transition is not accompanied with ferroelectricity. At 3K, we observed magnetic superlattice reflections at Q = (0, k, l$$pm$$$$delta$$) and (h, 0, l$$pm$$$$delta$$) (h, k and l = even) with $$delta$$$$sim$$ 0.488 by the powder neutron diffraction. By the combined studies of neutron diffraction and magnetization data, the magnetic structure of Li$$_{2}$$ZrCuO$$_{4}$$ is proposed. On the bases of the obtained data, reasons for absence of ferroelectricity in Li$$_{2}$$ZrCuO$$_{4}$$ are discussed.
