  CaFe$_{2}$O$_{4}$ is an anisotropic $S={5\over 2}$ antiferromagnet with two
competing $A$ ($\uparrow \uparrow \downarrow \downarrow$) and $B$ ($\uparrow
\downarrow \uparrow \downarrow$) magnetic order parameters separated by static
antiphase boundaries at low temperatures. Neutron diffraction and bulk
susceptibility measurements, show that the spins near these boundaries are
weakly correlated and a carry an uncompensated ferromagnetic moment that can be
tuned with a magnetic field. Spectroscopic measurements find these spins are
bound with excitation energies less than the bulk magnetic spin-waves and
resemble the spectra from isolated spin-clusters. Localized bound orphaned
spins separate the two competing magnetic order parameters in
CaFe$_{2}$O$_{4}$.
