Incommensurate magnetic strcture of Fe3Ga4 under zero and non-zero magnetic field

Due to potential application in future spintronic devices, studying the nature of topological magnetism has gained tremendous attention in recent times. Here, using the high resolution diffractometer, WISH, we aim at determining the complicated magnetic structure of one such compound, Fe_3Ga_4. This system shows finite topological Hall effect even above room temperature. The proposed experiment will shed light on the real (and reciprocal) space nontrivial spin arrangement, which results in such exotic effects. Along with addressing the contradicting arguments about the zero field state, we will go one step forward and try to resolve the magnetic field-induced spin textures. Due to the nature of topological magnetism observed in Fe_3Ga_4, results of this study will have impact on both fundamental as well as application oriented research in the field.
