Multishell contribution to the Dzyaloshinskii-Moriya spiraling in MnSi-type crystals

Exchange bias driven by Dzyaloshinskii-Moriya interactions.

The exchange bias effect in a compensated IrMn3/Co(111) system is studied using multiscale modeling from ab initio to atomistic spin model calculations. We evaluate numerically the out-of-plane hysteresis loops of the bilayer for different thicknesses of the ferromagnetic layer. The results show the existence of a perpendicular exchange bias and an enhancement of the coercivity of the system. T...

Wide-Range Probing of Dzyaloshinskii–Moriya Interaction

The Dzyaloshinskii-Moriya interaction (DMI) in magnetic objects is of enormous interest, because it generates built-in chirality of magnetic domain walls (DWs) and topologically protected skyrmions, leading to efficient motion driven by spin-orbit torques. Because of its importance for both potential applications and fundamental research, many experimental efforts have been devoted to DMI inves...

Quantum criticality of the kagome antiferromagnet with Dzyaloshinskii-Moriya interactions

The nearest neighbor spin S = 2 antiferromagnet on the kagome lattice has been the focus of extensive theoretical and experimental study because it is a prime candidate for realizing a ground state without antiferromagnetic order. On the experimental side, much attention has focused on the S = 1/2 compound herbertsmithite ZnCu3(OH)6Cl2. It has J ⇡ 170 K and no observed ordering or structural di...
