Diffraction paten of a Heisenberg-Kitaev Quantum Spin Liquid candidate Li2RhO3

We propose to continuous our investigation of the magnetic diffraction pattern of the potential Kitaev spin liquid compound Li2RhO3. Moderate spin orbit coupling in the Rh4+ ion is expected to results in a ground state doublet which in combination with the honeycomb structure of RhO6 edge-sharing octahedral, gives rise to highly directional Kitaev interactions. Our previous powder measurements of Li2RhO3 performed on WISH revealed the magnetic Bragg peak at |Q|=0.97 Å-1 suggesting that Li2RhO3 develops either zig-zag or stripy magnetic order with the ordering wave vector k = [0,1,1/2]. The goal of this experiment is to extract an accurate value of TN and the critical exponent by measuring the intensity of the magnetic Bragg peak at different finite temperatures.
