Neutron scattering study of the antiferromagnetic ordering in UPt sub 3 at mK-temperatures

Neutron scattering experiments have been performed in order to study the antiferromagnetic correlation in UPt sub 3 at ultralow temperatures. The (0.5 0 1) antiferromagnetic peak was observed down to 20 mK. The line width exhibits a remarkable narrowing with decreasing temperature, and a resolution-...

Description
Summary:Neutron scattering experiments have been performed in order to study the antiferromagnetic correlation in UPt sub 3 at ultralow temperatures. The (0.5 0 1) antiferromagnetic peak was observed down to 20 mK. The line width 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 UPt sub 3 .
