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