      abstract     = {CaFe2O4 is a S=52 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 order parameters result in magnetic
                      antiphase boundaries along c which freeze on the time scale
                      of ∼1  ns at the onset of magnetic order at 200 K.
                      Using high resolution neutron spectroscopy, we find
                      quantized spin wave levels and measure 9 such excitations
                      localized in regions ∼1–2 c-axis lattice constants in
                      size. We discuss these in the context of solitary magnons
                      predicted to exist in anisotropic systems. The magnetic
                      anisotropy affords both competing A+B orders as well as
                      localization of spin excitations in a classical magnet.},
