Abstract
We present a design for a piezoelectric-driven uniaxial stress cell suitable for use at ambient and cryogenic temperatures and that incorporates both a displacement and a force sensor. The cell has a diameter of 46 mm and a height of 13 mm. It can apply a zero-load displacement of up to similar to 45 mu m and a zero-displacement force of up to similar to 245 N. With combined knowledge of the displacement and force applied to the sample, it can quickly be determined whether the sample and its mounts remain within their elastic limits. In tests on the oxide metal Sr2RuO4, we found that at room temperature serious plastic deformation of the sample onset at a uniaxial stress of similar to 0.2 GPa, while at 5 K the sample deformation remained elastic up to almost 2 GPa. This result highlights the usefulness of in situ tuning, in which the force can be applied after cooling samples to cryogenic temperatures. Published under license by AIP Publishing.
