Abstract

DyB₂ C₂ with an antiferroquadrupolar (AFQ) transition at T_Q = 24.7 K was diluted by non-magnetic Y and examined by specific heat experiments under magnetic fields in order to elucidate its magnetic phase transition behavior. Basically, the phase diagram of Dy_0.4 Y_0.6 B₂ C₂ is similar to that of DyB₂ C₂. In Dy_0.5 Y_0.5 B₂ C₂, the AFQ transition occurs simultaneously with the antiferromagnetic transition at T_N.
