Figure 1

(Color online) (a) Intensity at the incommensurate reflection (0.3,0.3,0.7) measured in the SF and NSF channels at 4 K. (b) Comparison of the $Q$ dependence of incommensurate reflections (circles) to the square of the magnetic form factor (solid line). (c) $I\left(4\text{K}\right)-I\left(150\text{K}\right)$ measured in the SF and NSF channels for the broad ferromagnetic scattering around (0,0,1). There is some subtracted intensity that falls outside of the data range shown which comes from the change in the lattice constant. Note that the error bars in figures which display raw intensity represent a statistical uncertainty of $\pm 1\sigma$ and the error bars of fitted values in figures (i.e., integrated intensities) represent the $1\sigma$ errors as determined from the covariance matrix.Reuse & Permissions

The region around $\left(\overline{0.3},\overline{0.3},0.7\right)$ is shown in the inset.Reuse & Permissions

(Color online) Evolution of the integrated intensity corresponding to the one-dimensional (1D) fitted Lorentzian component, shown in (a), and the 1D fitted Gaussian component, shown in (b), with increasing and decreasing field.
