Abstract

The application of an electric field along the b axis of $K_{0.30}$ ${MoO}_{3}$ in the charge-density-wave (CDW) state causes a metastable loss of transverse order as measured by x-ray diffraction. In contrast, scans parallel to the CDW modulation wave vector are resolution limited with no field-induced change of position or width. These results provide structural evidence for metastable CDW states previously seen in transport measurements.

We find that if we look carefully, small-scale switching can be observed in many samples of $K_{0.30}$ ${MoO}_{3}$ _ in the region near threshold, particularly at temperatures below 77 K. The amount of switching is small as compared to materials such as Fe-doped ${NbSe}_{3}$ ; _ see M. P. Everson and R. V. Coleman, Phys. Rev. B 28, 6659 (1983).
