The magnetic ordering in NdMn2O5 single crystal has been studied by the neutron scattering, including XYZ-polarization analysis. At TN ≈ 30 K the onset of the long-range magnetic order with incommensurate wave vector k = (0.5 0 ~0.36) is observed. Below 30 K two magnetic phases are observed with propagation vectors close each other: k1 = (0.5 0 kz1), k2 = (0.5 0 kz2). kz1, kz2 components increase monotonously with temperature decrease down to 25 K, then remain to be constant with values kz1 = 0.384(2), kz2 = 0.395(2). Two reorientation transitions were observed at ~ 20 K and at ~ 5 K.
