Show affiliationsThe authors report neutron scattering observations of the stabilization of the locked-in phase with spiral pitch of 1/4c* in holmium by a magnetic field applied along the b-axis. In contrast to a theoretical suggestion that stabilization of this phase by a c-axis field was due to imperfect alignment causing a small component of field in the basal plane, it is shown that the effect of a field of 3 T along the b-axis is to stabilize the phase over a somewhat smaller temperature range than the stabilized range in an identical field along the c-axis. The centre of the locked-in phase moves from 96 K in zero field to 103 K in a b-axis field of 3 T, while in a similar c-axis field the phase remains centred at around 96 K. The authors also observe a locked-in phase at a wave-vector of 5/18, in the temperature range from 125 K to the Neel transition.
