Neutron scattering experiments have been performed in order to study the antiferromagnetic correlation in UPt3 at ultralow temperatures. The (0.5 0 1) antiferromagnetic peak was observed down to 20 mK. The linewidth exhibits a remarkable narrowing with decreasing temperature, and a resolution-limited peak is observed below 20 mK. This is direct evidence for the long-range antiferromagnetic correlation in UPt3.
