Abstract
Neutron topographic experiments show that the simultaneous application of an uniaxial stress and a magnetic field when cooling a MnF2 crystal through TN favours one type of 180° antiferromagnetic domain. This appears to be related to the piezomagnetism of MnF2, in spite of the weakness of this effect, which was measured in our case by a SQUID.
