A neutron-diffraction experiment was performed to investigate the effect of a magnetic field on the antiferromagnetic order in the heavy-fermion superconductor UPt{sub 3}. Our results show that a field in the basal plane of up to 3.2 T, higher than {ital H}{sub {ital c}2}(0), has no effect: it can neither select a domain nor rotate the moment. This has a direct impact on current theories for the superconducting phase diagram based on a coupling to the magnetic order. {copyright} {ital 1996 The American Physical Society.}
