摘要：
The weak magnetic order of the heavy-fermion superconductor UPt3 has been investigated by elastic neutron-scattering measurements in magnetic fields up to 12 T along the a and c axes of the hexagonal crystal structure. The small antiferromagnetically ordered moment of 0.02 mu(B)/(U atom) shows only a weak dependence on the applied magnetic field and no sign of a domain repopulation for B parallel to a. In high magnetic fields an increase in the magnetic con-elation length is observed for magnetic fields along the c axis.
