Abstract : The magnetic moments in MnP order below 50 °K in a spiral arrangement, and a polarized-neutron experiment shows for the first time that spirals of opposite senses may occupy unequal volumes of a single crystal. The domain population was changed by annealing the crystal at 600 °C, but not by the application of magnetic fields. A comparison between the properties of the double spiral in MnP and the single spirals, as in holmium, suggests that the domain populations in the former may be more easily influenced by external forces.
