Tuning the antiferromagnetic helical pitch length and nanoscale domain size in ${\mathrm{Fe}}_{3}{\mathrm{PO}}_{4}{\mathrm{O}}_{3}$ by magnetic dilution
Abstract
The insulating magnetic material Fe_{3}PO_{4}O_{3} features a noncentrosymmetric lattice composed of Fe^{3}+ triangular units. Frustration, due to competing nearneighbor (J_{1}) and nextnearestneighbor (J_{2}) antiferromagnetic interactions, was recently suggested to be the origin of an antiferromagnetic helical ground state with unusual needlelike nanoscale magnetic domains in Fe_{3}PO_{4}O_{3}. Magnetic dilution is shown here to tune the ratio of these magnetic interactions, thus providing deeper insight into this unconventional antiferromagnet. Dilution of the Fe^{3+} lattice in Fe_{3}PO_{4}O_{3} was accomplished by substituting nonmagnetic Ga^{3+} to form the solid solution series Fe_{3x}Ga_{x}PO_{4}O_{3} with x=0.012, 0.06, 0.25, 0.5, 1.0, 1.5. Magnetic susceptibility and neutron powder diffraction data from this series are presented. A continuous decrease of both the helical pitch length and the domain size is observed with increasing dilution up to at least x=0.25, while for x≥0.5, the compounds lack longrange magnetic order entirely. The decrease in the helical pitch length with increasing x can be qualitatively understood by reduction of the ratio of J_{2}/J_{1} in the Heisenberg model, consistent with meanfield considerations. Intriguingly, the magnetic correlation length in the ab plane remains nearly equal to the pitch length for each value of x≤0.25, showing that the two quantities are intrinsically connected in this unusualmore »
