Query: Magnetic Excitations in the Quasi-1D Ising-like Antiferromagnet
  TlCoCl$_3$   Neutron inelastic scattering measurements have been performed in order to
investigate the magnetic excitations in the quasi-1D Ising-like antiferromagnet
TlCoCl$_3$. We observed the magnetic excitation, which corresponds to the
spin-wave excitation continuum corresponding to the domain-wall pair excitation
in the 1D Ising-like antiferromagnet. According to the Ishimura-Shiba theory,
we analyzed the observed spin-wave excitation, and the exchange constant $2J$
and the anistropy $\epsilon$ were estimated as 14.7 meV and 0.14 in TlCoCl$_3$,
respectively.
