In order to elucidate quadrupolar and magnetic interactions in the antiferroquadrupolar (AFQ) and antiferromagnetic (AFM) ordering compound DyB2C2, 161Dy Mössbauer spectroscopy was performed on the Y-diluted system Dy1-xYxB 2C2. The results reveal that the AFQ and AFM interactions compete with each other. The magnetic hyperfine field that is proportional to the magnetic moment strongly depends on the number and site of Y substitution in the nearest neighbors. Some kinds of Y substitution in the neighbors cause larger hyperfine fields than that in DyB2C2.
