a Contour map of neutron scattering intensity on the reciprocal lattice (h, 1, l) plane at 2 K and 0 T. The nuclear and magnetic peaks are indicated by light-blue and green circles, respectively. b Neutron scattering intensity profile along the (h, 1, 0) line around the center of h = 4/3 and h = 8/3 at several magnetic fields from 0 to 6.5 T. For clarity, each data was shifted vertically by a constant interval. c Magnetic field dependence of the integrated intensity of the (4/3, 1, 0) magnetic peak (red squares) and (8/3, 1, 0) magnetic peak (green circles). Magnetization normalized by the saturation value at 14 T (M/Ms) and the calculated sin2θ are also plotted with solid orange line and broken blue line, respectively. Here, θ [= arccos(M/Ms)] is defined as the angle of the Gd moments tilted from the b-axis to the ac-plane. d Schematic of the magnetic structure of Gd local moments under magnetic fields.
