Tuning the antiferromagnetic helical pitch length and nanoscale domain size in Fe${}_3$PO${}_4$O${}_3$ by magnetic dilution

M. J. Tarne, M. M. Bordelon, S. Calder +2

The insulating magnetic material Fe3PO4O3 features a non-centrosymmetric lattice composed of Fe^{3+} triangular units. Frustration, due to competing near neighbor ($J_1$) and next…
