One of the offshoots of the discovery of superconductivity (SC) in the Y-Ni-B-C system is the coexistence of SC and magnetism in RNi2B2C (R = Er, Ho, Tm). Here we report our observation of SC (Tc≈6 K) and magnetic order (TN≈11 K) in polycrystalline DyNi2B2C. This is one of a few systems where SC sets in with Tc < TN. From the known systematics of Tc and TN in borocarbide systems, we expect YbNi2B2C to exhibit SC around 12 K. However, our resistivity measurements in YbNi2B2C do not reveal SC down to 1.5 K.
