High-resolution x-ray-scattering study of charge-density-wave modulation in chromium

Abstract

We present a high-resolution x-ray-scattering study of the charge-density-wave modulation in chromium. The wave vector at $2Q$ was found to vary continuously between 170 and 10 K, consistent with the results of earlier neutron-diffraction studies of the magnetic wave vector at $Q$. Lock-in transitions, such as have been observed in rare-earth magnets, are apparently not present in chromium.
