In-plane anisotropic response to the uniaxial pressure in the hidden order state of URu${}_2$Si${}_2$

Xingyu Wang, Dongliang Gong, Bo Liu +11

We studied the uniaxial-pressure dependence of the resistivity for URu${}_{2-x}$Fe${}_x$Si${}_2$ samples with $x$ = 0 and 0.2, which host a hidden order (HO) and a large-moment antiferro…
