Electronic properties of a heavy fermion U Ru0.92Rh0.08 2Si2 single crystal

U Ru0.92Rh0.08 2Si2, prepared using a modified Czochralski method. Our study, that also includes neutron diffraction results, shows all the heavy fermion signatures of pristine URu2Si2; however, the superconductivity, hidden order, and remnant weak antiferromagnetic orders are absent. Instead, the ground state of the doped system can be classified as a spin liquid that preserves the heavy fermion character. U Ru0.92Rh0.08 2Si2 exhibits a short range magnetic order distinguished by reflections of a Lorentzian profile at qIII 1 2 1 2 1 2 positions that disappear above 15 K. The short range order seems to be a precursor of a long range magnetic order that occurs with higher Rh concentration. We indicate that these short range fluctuations involve, at least partially, inelastic scattering processe
