NMR Investigation of antiferromagnetism and coherence in URu${}_2$Si${}_{2-x}$P${}_x$

K. R. Shirer, M. Lawson, T. Kissikov +5

We report ${}^{31}$P and ${}^{29}$Si NMR in single crystals of URu${}_2$Si${}_{2-x}$P${}_x$ for $x=0.09$ and $x=0.33$. The spectra in the $x=0.33$ sample are consistent with a homogenous com…
