Partial Antiferromagnetic Helical Order in Fe${}_3$PO${}_4$O${}_3$

C. L. Sarkis, M. J. Tarne, J. R. Neilson +4

Magnetic frustration in Fe${}_3$PO${}_4$O${}_3$ has been shown to produce to an unusual magnetic state below T${}_N=163$ K, where incommensurate antiferromagnetic order is restricted to…
