Isoelectronic perturbations to $f$-$d$-electron hybridization and the enhancement of hidden order in URu${}_2$Si${}_2$

C. T. Wolowiec, N. Kanchanavatee, K. Huang +8

Electrical resistivity measurements were performed on single crystals of URu${}_2-x$Os${}_x$Si${}_2$ up to $x$ = 0.28 under hydrostatic pressure up to $P$ = 2 GPa. As the Os concentratio…
