Abstract
We report magnetic properties and the phase diagram of NdB2C2 which has the same tetragonal LaB2C2 crystal structure as that of the antiferroquadrupol ar ordering material, DyB2C2. NdB2C2 is an uniaxial anisotropic antiferroma gnet with T-N = 8.8 K. The propagation vector in the magnetic ordered state below T-N is k = [100]; the coupling between the nearest neighbour magneti c moments in the c-plane is antiferromagnetic, and that along the [001] dir ection is ferromagnetic.
