Gd substitution in DyB2C2 enhances the antiferromagnetic (AFM) interaction and weakens the antiferroquadrupolar (AFQ) interaction. In Dy0.8Gd0.2B2C2, two successive transitions occur. By performing resonant X-ray scattering measurements, we confirmed the AFQ ordering temperature TQ=18.0K and the Néel temperature TN=19.5K; TN is higher than TQ in Dy 0.8Gd0.2B2C2, in contrast to DyB2C2. There exists an AFM phase between TQ and TN, and the magnetic structure is described by k=[100]. This kind of AFM phase is also observed in HoB2C2 and TbB2C2, although the magnetic structures of these compounds are long-periodic ones.
