Outline of Final Research Achievements |
We performed synchrotron X-ray backscattering measurements on a single crystal of URu2Si2. We measured the (8 8 0) Bragg peak, and observed no signature of broadening and splitting due to hidden order below 17.5 K. Detailed analysis of the peak width reveals that the tetragonal fourfold rotational symmetry of URu2Si2 is conserved in hidden order within the experimental accuracy.
