Abstract :
Single crystals of (PO2)4(WO3)2m (m=13) have been studied by x-ray diffuse scattering and transport (resistivity, Hall effect and thermopower) measurements. Three instabilities are found at Tc0=510K, Tc1=550K and Tc2=160K with modulations of wavevector q0=(0.5,0,0), q1=(0.053,0.016,?) and q2=(0.178,0.145,?). The q1 an q2 instabilities are attributed to charge density waves and the q0 one to an antiferroelectric distortion.
