Uniaxial pressure induced spin-density wave order in CeAuSb2

We propose to apply uniaxial strain to induce a spin-density wave (SDW) modulation in CeAuSb2. Neutron diffraction measurements show this system has a tendency to order along the [010] direction which can be stabilised with an applied field. Recent transport measurements show that compressive strain along the a-axis induces a first-order transition into a new phase marked by jump in the resistivity along the b axis, which in materials such as Sr3Ru2O7 is the signature of an SDW with q_SDW along [010] (parallel to the axis of enhanced resistivity).
