        Effect of the magnetization in different directions on the (111) Fe₃O₄ neutron-diffraction peak is shown.  The pronounced dependence of neutron scattering intensity on magnetization direction suggests that the reflection might have interesting application as a fast-neutron shutter.  In a single-crystal reflection large neutron currents are attainable and rapid field variations with the small fields required for saturation of single crystals can be achieved in this or other members of the ferrite series.  9 refs. given.
