Abstract
In order to clarify the magnetic nature of a delafossite-type oxide, CuCr1-xMgxO2CuCr1-xMgxO2 (x=0x=0 and 0.03), we have performed zero field (ZF-) and weak transversal field (wTF-) μ+SRμ+SR measurements in the temperature range between 1.8 and 50 K using polycrystalline samples. The wTF-μ+SRμ+SR measurements suggested that both samples undergo a magnetic transition at Tm=26K, clarifying that TmTm is not altered by the Cr3+Cr3+ substitution with Mg2+Mg2+. The ZF-μ+SRμ+SR measurements indicated the existence of a clear muon-spin precession (∼50MHz at T→0K) signal for the x=0x=0 sample below TmTm, indicating a long-range antiferromagnetic order state, whereas the absence of long-range order for the x=0.03x=0.03 sample even at 1.8 K.
