In order to clarify the magnetic nature of a delafossite-type oxide, CuCr_1–xMg_xO₂ (x = 0 and 0.03), we have performed zero field (ZF-) and weak transversal field (wTF-) μ⁺SR measurements in the temperature range between 1.8 and 50 K using polycrystalline samples. The wTF-μ⁺SR measurements suggested that both samples undergo a magnetic transition at T_m = 26 K, clarifying that T_m is not altered by the Cr³⁺ substitution with Mg²⁺. The ZF-μ⁺SR measurements indicated the existence of a clear muon-spin precession (∼50 MHz at T → 0 K) signal for the x = 0 sample below T_m, indicating a long-range antiferromagnetic order state, whereas the absence of long-range order for the x = 0.03 sample even at 1.8 K.
