Magnetic properties were investigated on the single-crystalline HoB2C2 compound with the tetragonal structure. An antiferromagnetic (AFM) transition occurs at TN = 5.8 K. At TQ = 5.0 K, a spin-reorientation transition occurs, and spontaneous magnetization appears along the [1 0 0]- and [1 1 0]-axis. The magnetization behavior below TQ is well interpreted by postulating the magnetic structure similar to that of the antiferroquadrupolar (AFQ) ordering compound DyB2C2. Below TQ, the AFQ ordering coexists competitively with the AFM ordering. The pure AFQ ordered phase is confirmed only in the magnetic fields applied along the [1 1 0]-axis.
