A metastable state is defined by the spatial phase configuration of a pinned charge-density wave (CDW) and can be changed by varying the field or the temperature. Normally one associates metastable states with hysteresis in the static properties of the CDW, however, in Ko.30MoO 3 at low temperature
MSssbauer studies have been performed between 6 K and 300 K on single crystals of 57Fe-doped K0.30MoO 3. The spectra show three doublets. Two of them (B and C) are assigned to 57Fe substituted on the K sites. A strong line broadening below 120 K indicates that the Fe impurities are strong pinning ce
