Chemical pressure tuning of URu${}_2$Si${}_2$ via isoelectronic substitution of Ru with Fe

Pinaki Das, N. Kanchanavatee, J. S. Helton +8

We have used specific heat and neutron diffraction measurements on single crystals of URu${}_{2-x}$Fe${}_x$Si${}_2$ for Fe concentrations $x$ $\le$ 0.7 to establish that chemical substi…
