Superspace approach to the superstructures of CDW compounds and low-dimensional magnets

Abstract
Studies of the incommensurate or commensurate superstructures of low-dimensional crystals provide detailed information on the location of the Charge-density wave or the magnetic order. Accordingly the combined charge- and magnetic order is analysed in NaV2O5, and the 2-dimensional CDW is characterized in the phosphate bronze (PO2)4(WO3)8. It is shown that the superspace approach to the structure is essential for a succesful analysis of the simple, 4-fold superstructure of NaV2O5.
