Resonant ultrasound studies of Fe<sub>x=0.33</sub>NbS<sub>2</sub>

ORAL

Abstract

The intercalated transition metal dichalcogenide Fex=0.33NbS2 appears to exhibit frustrated antiferromagnetism. The orientation of its antiferromagnetic order can be switched by the application of electrical currents [1]. Similar behavior at room temperature could form the basis of a new generation of magnetic memory storage. However, the specific magnetic order of Fex=0.33NbS2 and how it evolves with temperature have not been exactly determined, leaving open questions about the microscopic mechanism of switching. Resonant Ultrasound Spectroscopy—a study of the material’s mechanical resonances—can shed light on the magnetic order in Fex=0.33NbS2.
