A recent hot topic in condensed matter is the discovery and successive study of skyrmions in materials such as MnSi or Cu2OSeO3. By tuning the magnetic field and temperature, the magnetic defects form a periodic lattice, the skyrmion crystal. Part of the excitement stems from the possibility of harnessing the topological aspect of these spin textures as a promising avenue for spintronics technology. These special states sit near more conventional incommensurate helical structures. Recent work on the noncentrosymmetric Fe3PO7 whose lattice contains AFM coupled triangular Fe3+ ions suggests that it hosts nanosized helical magnetic domains with abundant magnetic defects below 163K. However, its precise magnetic structure is still unclear as conical and helical structures are suggested. Our proposal is dedicated to understanding the magnetic configuration and topological defects in Fe3PO7.
