Аннотация:In this letter, we use an analytical method for the estimation of magnetic properties of a wide range of ferromagnetic and antiferromagnetic single-atomic and biatomic chains.It is found that biatomic chains can be used as a bit of information at higher temperatures than temperatures for the same single-atomic chains. At the same time, the ratio between the spontaneous and induced remagnetization times is lower in the case of biatomic chains. According to our analysis, Co chains on a Rh(553) surface seem the most conducive to the creation of stable bits of information. The effects of nitriding the substrate or oxidation of the atomic chain are discussed. An analysis of magnetodynamic properties of ferromagnetic chains shows that the usage of atomic chains gives an opportunity to construct magnetic materials with a wide range of physical properties.
