Paper: Frustrated Heisenberg J1-J2 model within the stretched diamond lattice of LiYbO2

January 14, 2021

Our paper exploring the magnetic ground state of LiYbO2 was published today in Physical Review B.  LiYbO2 is an interesting manifestation of a network of Jeff=1/2 Yb ions decorating a stretched diamond lattice.  Our experiments unveil an unusual sequence of magnetic order upon cooling that forms a helical order in the ground state.  Theoretical modeling by Chunxiao Liu in Leon Balent's group captures the properties of this material within a frustrated Heisenberg J1-J2 model on this elongated diamond lattice.
