We have performed specific heat experiments on Ho1-xTb xB2C2 (0≤x≤1.0) in order to clarify the similarity and difference between anomalous antiferromagnetic phases of H0B 2C2 and TDB2C2. H0B 2C2 undergoes an antiferromagnetic (AFM) transition at TN= 5.9 K and an an- tiferroquadrupolar (AFQ) transition at T Q= 4.5 K. TDB2C2 shows only an AFM transition at TN= 21.7 K. Although TN changes gradually with increasing x, TQ hardly decreases up to x = 0.6. This unusual result indicates that the Tb atoms seem to support the AFQ order in H0B 2C2. However, judging from an entropy change at T Q, it is supposed that the Tb atoms do not participate in the AFQ order.
