Cheong CaFe 2 O 4 is a S = 5 2 anisotropic antiferromagnet based upon zig-zag chains having two competing magnetic structures, denoted as the A ( ↑ ↑ ↓ ↓ ) and B ( ↑ ↓ ↑ ↓ ) phases, which differ by the c -axis stacking of ferromagnetic stripes. We apply neutron scattering to demonstrate that the competing A and B phase ord… [Phys. Rev. Lett. 117, 017201] Published Tue Jun 28, 2016
