Four different forms of local order that give rise to diffuse neutron and x-ray scattering in the relaxor ferroelectric series PMN-xPT are identified via broad, three-dimensional surveys of reciprocal space. Compositionally-dependent measurements reveal how the local ordering correlates with dielectric and electro-mechanical properties as well as with long-range polar order.
