Abstract: We report on a single-crystal neutron-diffraction study of the evolution of the antiferromagnetic order in the heavy-fermion compound CePd1-x NixAl which exhibits partial geometric frustration due to its distorted kagome structure. The magnetic structure is found to be unchanged with a propagation vector Q(AF) approximate to (0.500.35) for all Ni concentrations x up to x(c) approximate to 0.14. Upon approaching the quantum critical concentration xc, the ordered moment vanishes linearly with Neel temperature TN, in good agreement with CePdAl under hydrostatic pressure. For all Ni concentrations, substantial short-range magnetic correlations are observed above TN as a result of frustration.
