"Magnetic orderings of XY-pyrochores"

Prof. Haidong Zhou , University of Tennessee
[Host: Seunghun Lee]

ABSTRACT:

Due to the geometrically frustrated lattice and effective spin-1/2, the XY pyrochlores Er₂Ti₂O₇ and Yb₂Ti₂O₇ exhibit exotic magnetic ground states related to quantum spin fluctuations. In this talk, we presented our recent studies on the magnetic orderings of new XY pyrochlores Er₂Ge₂O₇ and Yb₂Ge₂O₇. Then we tried to unify the magnetic orderings of all studied XY pyrochlores Er₂B₂O₇ and Yb₂B₂O₇ (B = Sn, Ti, and Ge) through the chemical pressure effects based on the theoretically proposed phase diagram.
