Abstract

We present bulk magnetic and transport measurements and x-ray resonant scattering measurements on U(Pd1-xPtx)3 for x = 0.005 and 0.01, which demonstrate the high sensitivity of the quadrupolar order in the canonical antiferroquadrupolar ordered system UPd3 to doping with platinum. Bulk measurements for x = 0.005 reveal behavior similar to that seen in UPd3, albeit at a lower temperature, and x-ray resonant scattering provides evidence of quadrupolar order described by the Qxy order parameter. In contrast, bulk measurements reveal only an indistinct transition in x = 0.01, consistent with the observation of short-range quadrupolar order in our x-ray resonant scattering results.
