DESCRIPTION:Speaker: David MacNeill\nhosted by Johannes Fink\nAbstract: Lay
 ered magnetic insulators that can be exfoliated to the ultrathin limit are
  highly desirable\, as we can potentially create topological states and st
 udy electron correlations by incorporating them in van der Waals heterostr
 uctures. Such materials were finally realized in 2017 with the isolation o
 f monolayer CrI3 and bilayer CrGeTe3. However\, this field is in its infan
 cy and few-layer films have complex properties different from bulk\, such 
 as the ferromagnetic to antiferromagnetic transition in CrI3. In this talk
 \, I will discuss our isolation and characterization of the few-layer chro
 me trihalides CrI3 and CrCl3. We combine electron tunneling\, magneto-opti
 cal\, and Raman measurements\, to arrive at a consistent picture correlati
 ng structural and magnetic properties of the films. The focus will be on e
 lectronic detection of magnetic states in CrI3 and CrCl3 using spin-filter
  tunneling of electrons through magnetic insulating barriers.
