α-RuCl₃ has been attaining attention due to its possible realization of quantum spin liquid. While a signature of quantum spin liquid was observed in this material [1], the result has been controversial due to discrepancies between samples [2,3]. Here, we report X-ray diffraction and resonant elastic X-ray scattering (REXS) studies on α-RuCl₃ crystals with distinct magnetic transition temperature of T_N = 7.2K and 6.5K. We find the sample with T_N = 6.5K exhibits a high degree of twinning, whereas the T_N = 7.2K sample primarily comprises a single domain of R3. We find that both samples had identical magnetic structure with magnetic moments pointing away from the honeycomb plane by α=31^○ ± 2^○. We argue that the identical moment directions across these samples suggest that intralayer magnetic Hamiltonian remains mostly unchanged regardless of T_N. Moreover, we propose that the observed sample-dependent variations in magnetic transition temperature within α-RuCl₃ can be attributed to the interlayer interaction.
