- Аннотация: A simple analytical method for the investigation of the magnetic properties of the finite-length biatomic chains proposed in the framework of the Heisenberg model with uniaxial magnetic anisotropy. The method allows to estimate the reversal time of magnetization of ferromagnetic and antiferromagnetic biatomic chains. Three cases have been considered: the spontaneous remagnetization, the remagnetization under the interaction with a scanning tunneling microscope, and the remagnetization under the external magnetic field. The applicability limits of the method have been discussed. Within its limits of applicability the method produces the results which are in a perfect agreement with those obtained with the use of the kinetic Monte Carlo simulations. As the examples, two physical systems have been considered: biatomic Fe chains on Cu2N/Cu(001) surface and biatomic Co chains on Pt(997) surface. The presented method is incomparably less time-consuming than the commonly used kinetic Monte Carlo simulations, especially in the cases of low temperatures or long chains.
