Magnetic anisotropy in the rare-earth honeycomb lattice YbCl<sub>3</sub>

POSTER

Abstract

The Kitaev quantum spin liquid (KQSL) is an exact solvable exotic state with bond-directional interactions in a honeycomb lattice [1]. Its potential applications in quantum information field attract a lot of attention. So far only a few KQSL candidates are available, such as honeycomb lattices α-RuCl3 and Na2IrO3 with strong spin-orbital coupling 4d (Ru) and 5d (Ir) elements [2-4]. All these lattices show the long-range zig-zag magnetic order at low temperature instead of KQSL states. Recently we found a new Kitaev candidate, the rare-earth honeycomb lattice YbCl3 with an effective spin-1/2, which presents a short-range magnetic order around 1.2 K and another kink at 0.6 K [7]. We investigated the magnetic ground state and magnetic anisotropy of YbCl3 using unpolarized/polarized neutron diffraction techniques, which will be the focus of the presentation.
