LASSP and A&EP SEMINAR

Tuesday, November 7, 2017 at 12:20pm to 1:45pm

Clark Hall, 700
Central Campus

Nandini Trivedi, Department of Physics, The Ohio State University, Columbus, OH, will present seminar. Professor Jeevak Parpia, host. 

Seminar Title: Novel magnetic states in 5d oxides

Abstract: The standard paradigm for magnetism in 3d Mott insulators starts with preexisting atomic moments that interact via superexchange interactions. The resulting ground states -- antiferromagnetic or spin liquid-- depend on the lattice structure and the degree of geometric frustration. I will contrast the situation for 5d oxides: magnetism in the absence of atomic moments (really!), the sensitive role of orbitals, canted magnetic phases in the presence of spin-orbit coupling, and the possibility of entangled orbital liquids.

Poster available.
