Проектирование элементарного передающего устройства на базе поверхностной наносистемы Co/Cu(111)

Abstract

Co adatoms on the Cu(111) surface are known to exhibit strong ferromagnetic character of the exchange interaction, if coupled directly, and explicit antiferromagnetic one, if separated by two Cu atoms [1]. Our calculations, carried out in terms of Heisenberg model, re-vealed a possibility to design an elementary transmitting unit by adjusting geometry of the system. The transmittance of the unit was found stable up to ≈100 Å (100 bonds of FM chain) in small magnetic fields (~1 meV) at room temperature.
