Scientific Achievement
In the layered antiferromagnet FexNbS2, stripe or zigzag magnetic order is stabilized for samples with Fe vacancies or Fe interstitials respectively, with a narrow phase coexistence region centered around stoichiometric Fe1/3NbS2.
Significance and Impact
This work shows that the rapid current-induced resistance switching in Fe1/3NbS2, an intriguing property for future antiferromagnetic spintronics devices, arises from the competition between two magnetic states that can be manipulated by engineering magnetic defects.
Research Details
- Neutron diffraction and bulk characterization measurements were combined to investigate the evolution of the magnetic ground state in FexNbS2 as a function of Fe-doping.
