Narrow central peak of the magnetization dynamics at and below Tc in the singlet-singlet ferromagnet LiTbF 4
Approaching the Curie temperature T c from above, a narrow relaxation peak appears in the dynamical form factor of the homogeneous magnetization on top of the broad, noncritical central intensity detected previously by dynamical susceptibility and neutron scattering work. Below T c, this central pea...

| Summary: | Approaching the Curie temperature
T
c from above, a narrow relaxation peak appears in the dynamical form factor of the homogeneous magnetization on top of the broad, noncritical central intensity detected previously by dynamical susceptibility and neutron scattering work. Below
T
c, this central peak substantially narrows and the resulting shape is described by an empirical model which couples the damping to two relaxation dynamics of unknown origin. |
