The compound (ND4)2[FeCl5(D2O)] has awakened a renewed interest owing to its recent classification as a new multiferroic material. We have recently investigated by means of single crystal and powder neutron diffraction the magnetic structure at zero magnetic field of (ND4)2[FeCl5(D2O)], observing a cycloidal magnetic structure propagating in the c-axis with k = (0, 0, 0.23) and with the magnetic moments lying in the ac plane, this propagation vector can be modulated applying external stimulus as pressure. In the previous proposal (number 5-15-607) we have proved that the pressure act as modulator in the magnetic structure. In this continuation proposal we ask beam time at D1B and D9 diffractometers to complete the previous studies.
