Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature. By suppressing the second-order metamagnetic transition in Sr3Ru2O7 to low temperatures with a magnetic field, the system can be driven through two distinct spin density wave phases near 8 T. Here we propose to use the WISH diffractometer to measure the effect of tilting the magnetic field on the magnetic order. This we would like to relate to the unusual magnetoresistance seen in this material.
