Figure 2: High-field neutron diffraction at momentum transfers close to Q1, at T=2 K.
From: Field-induced spin-density wave beyond hidden order in URu2Si2

Magnetic field dependence of the neutron-diffracted intensity (a) at momentum transfers Q=(Qh 0 0) and (b) at momentum transfers Q=(0.6 0 Ql), in fields up to 36.2 T, within field steps Δ(μ0H) of 0.5 T. (c) Qh and (d)Ql scans around the momentum transfer Q1=(0.6 0 0) under a magnetic field μ0H=36 T (field window Δ(μ0H)=1 T). The error bars ΔI are given by the square root of the neutron counts (). Open and full symbols correspond to rising and falling fields, respectively. The magnetic field H has been applied along the easy magnetic axis c with a tilt of 4.2° along a.
