a, Photographs of Sample F, showing the locations of the ac susceptibility coil, the hematite masks, and the force-sensing strain gauges. b, A view from the muon direction. The beam diameter is 1 cm. (c) A schematic of the sample holder, in which the moving portion is coloured blue. This holder slots into a force generator, described in Ref. 59. d, Force-displacement data for Samples D-F. For Sample D, a chip broke from one of the two pieces of Sr2RuO4 at a load of 500 N. For Samples E and F, the force-displacement relationships are straight lines, showing that the sample did not fracture under the load. Note that in Sample F the data fall on two distinct lines. This may have originated in a slip in the apparatus that altered the calibration of the displacement sensor; it is not of the form expected for damage to the sample.
