Abstract

Nuclear-magnetic-resonance measurements in incommensurate ${Rb}_{2}$ Zn ${Br}_{4}$ show the existence of regions where the modulation wave is floating. The floating regions coexist with other regions where the modulation wave is static. Impurity phase pinning and a roughening of the modulation wave at higher temperatures is proposed to account for these effects.
