Description
We have performed synchrotron X-ray backscattering measurements on a high-quality single crystal of URu2Si2 with RRR > 350. The obtained experimental results show that the tetragonal crystalsymmetry of this system is preserved in Hidden Order within the highest-ever spatial resolution for the detection of orthorhombicity (b' - a')/(b' - a') of ~ 1.0 x 10-5. We also present the tests for the reproducibility of magnetic torque measurements using the same single-crystalline sample to discuss the possible broken symmetry of URu2Si2.
