Thanks to the unique power of muon-spin spectroscopy, we found that the quasi-one-dimensional Co-Rh oxides A_n₊₂CoRh_nO_3n+3 (A=Ca,Sr; n=1, 2, and 3) exhibit a two-dimensional antiferromagnetic transition that ranges from T_N^on=185 K for n=1 to 125 K for n=3 with a transition width (ΔT) of about 80 K. The variation of T_N^on with n is explained by the increase in the distance between the neighboring CoRh_nO_3n+3 chains. Static magnetic order is observed below the end point of T_N (=T_N^on−ΔT) for each of the three samples. The existence of the two-frequency components in the zero field spectrum indicates the appearance of ferrimagnetic order for Ca₃CoRhO₆ below 20 K.
