چکیده
|
In this work, employing a tight-binding framework together with the conventional theory of elasticity, we discuss how strain-induced local deformations can be used as a means to affect ruderman-kittel-kasuya-yosida (rkky) interaction in zigzag nanoribbons of b$_2$s.we show that breaking inversion symmetry in zigzag b$_2$s nanoribbons (zbsnr), e.g., by introducing staggered sublattice potentials, play a key role in the modulation of their magnetic properties.the spatial and strain dependency of the exchange interaction in various configurations of the magnetic impurities are also evaluated.it is shown that that magnetic interactions between adsorbed magnetic impurities in b$_2$s nanoribbons can be manipulated by careful strain engineering of such systems. our results suggest that these tunable electronic and magnetic properties of zbsnrs mean they may find applications in spintronics and pseudospin electronics based on monolayer b$_2$s nanoribbons.

Abstract
|
In this work, employing a tight-binding framework together with the conventional theory of elasticity, we discuss how strain-induced local deformations can be used as a means to affect Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in zigzag nanoribbons of B$_2$S.We show that breaking inversion symmetry in zigzag B$_2$S nanoribbons (ZBSNR), e.g., by introducing staggered sublattice potentials, play a key role in the modulation of their magnetic properties.The spatial and strain dependency of the exchange interaction in various configurations of the magnetic impurities are also evaluated.It is shown that that magnetic interactions between adsorbed magnetic impurities in B$_2$S nanoribbons can be manipulated by careful strain engineering of such systems. Our results suggest that these tunable electronic and magnetic properties of ZBSNRs mean they may find applications in spintronics and pseudospin electronics based on monolayer B$_2$S nanoribbons.
