The phase diagram of the high-temperature cuprate superconductors encompasses a variety of intertwined phases. Typically the phase diagram is traversed using chemical doping or magnetic field, but uniaxial pressure offers an alternative clean tuning parameter. Recently, large a-axis uniaxial pressures in YBa₂Cu₃O_6.67 have been shown to stabilise a three-dimensional long-range-ordered charge density wave, analogous to that achieved with large c-axis magnetic fields, but at zero field [1]. Using GaAs-based Hall probe susceptometers, we have investigated the strain dependence of ∼1/8-doped YBCO with high spatial precision, up to pressures of at least 1.5 GPa, crossing the transition into long-range CDW order.
