The aim of this study is to compare the magnetic behavior of URu${}_{2}$Si${}_{2}$ under uniaxial stress along the $a$ axis with the behavior under hydrostatic pressure. Both are very similar, but uniaxial stress presents a critical stress ${\ensuremath{\sigma}}_{x}^{a}$ [0.33(5) GPa] that is smaller than the hydrostatic critical pressure ${p}_{x}$ (0.5 …
