Abstract
Applying Landau's theory we have determined the spin structure of neodymium crystal below TC= 19.3 K for the star of the vector q1 = µ1b1 + µ2b2. The corresponding cross-section for magnetic scattering of polarized neutrons yields the satellites (h ± q, 0, 0). Two pairs of satellites around the point (0, 1, 0) have lower intensities than the remaining ones.
