    • In this model the size of the superparamagnetic "particles" is estimated from the time-dependent kink density of the one-dimensional nearest-neighbor-exchange model in the infinite anisotropy (i. e., Ising) limit. Then these particles are considered as decoupled from each other but exposed to an external magnetic field and an anisotropy field, and the thermodynamics is described by classical Boltzmann statistics. In reality, the exchange energy is certainly much larger than the anisotropy energy also for the monatomic wires, and therefore the wire sections cannot be considered as decoupled, see, e.g., J. Shen et al., Phys. Rev. B 56, 2340 (1997). Therefore, it would be highly desirable to have a more rigorous treatment by calculating the dynamical structure factor for a one-dimensional chain with finite magnetic anisotropy and external magnetic field.
