Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron and hole pockets. Although the magnetic excitations in chromium have been investigated since the 1960's the large spin-wave velocity, large energy scale of the excitations and the requirement to have good wavevector and energy resolution in all directions means there are a number of unanswered questions. Here we propose to apply the new MERLIN spectrometer and the multi-phi data collection technique to this special element. We hope to reveal the detailed structure of the magnetic excitations in the 0-100 meV range and possibly observe new interband contributions to the response.
