Magnetic structure of monoaxial chiral antiferromagnet Fe<sub>1/3</sub>NbS<sub>2</sub> and its implications
ORAL
Abstract
The intercalated transition metal dichalcogenide Fe1/3NbS2 has recently attracted significant interest due to its demonstrated peculiar coupling between the magnetic and the electronic degrees of freedom, paving the way for novel antiferromagnetic spintronics applications. The basis for understanding this coupling, is the interpretation of the magnetic structure of this material. With this motivation in mind, we have recently collected single crystal neutron diffraction data on Fe1/3NbS2 over a large volume of reciprocal space using neutron wavelength-resolved Laue diffraction at the SNS TOPAZ instrument. In this talk, I will discuss these measurements and the results of our magnetic structure determination for Fe1/3NbS2 using this data. I will further discuss predictions based on this magnetic structure for a static magnetic Kerr effect, and confirmation of this phenomenon by optical experiments performed at the University of Illinois. Finally, I will discuss the implications of our work for novel transport behaviors in the larger family of intercalated transition metal dichalcogenides.
