Abstract
Huge increase of thermal conductivity ri is observed at the phase transitio n in stoichiometric NaV(2)O5. This anomaly decreases and gradually goes awa y with deviation from the stoichiometry in Na1-xV2O5 (x = 0.01, 0.02, 0.03, and 0.04). These properties are compared with behaviour of pure and Zn-dop ed CuGeO3 where only modest kinks in k(T) curves have been observed at spin -Peierls transition. (C) 1999 Elsevier Science B.V.
