摘要：

The behaviors of 2k(F) and 4k(F) charge-density waves (CDWs) coexisting with spin-density waves (SDWs) in the title compounds were studied by diffuse X-ray scattering down to 1.6 K. It was found in the PF6 compound that CDWs disappear below 3-4 K while they are present in the temperature range between 4 and 12 K, the SDW onset temperature. This behavior is possibly related to the subphase structure of SDW. In the AsF6 compound, the amplitude of CDW is very small, which is related to the difference between the heat capacities of these two compounds observed previously. (C) 1999 Elsevier Science Ltd.
