a QL-scan along the (0.5, 0.5, L) line (range 0.2 < L < 1.2) obtained at 10 K. b T-QL projection of the temperature dependence of magnetic intensities along the (0.5, 0.5, L) line centered around the (½ ½ ½) position for the single crystal. c Temperature dependence of the neutron integrated intensities of CM (1/2 1/2 1/2) [k1] and ICM (1/2 1/2 1/2±qS) [k2] magnetic reflections. d Evolution with temperature of the discommensuration qS of the spiral phase. The twist angle φ (canting) formed by the two spins of a bipyramid in the spiral phase is also shown (φ = 2πqS). The error bars in (a) are statistical errors and in (c) and (d) the standard deviations obtained from the Gaussian least-square fits using the FullProf Suite package33.
