Abstract

Magnetic properties were investigated on the single-crystalline HoB₂C₂ compound with the tetragonal structure. An antiferromagnetic (AFM) transition occurs at T_N = 5.8 K. At T_Q = 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 T_Q is well interpreted by postulating the magnetic structure similar to that of the antiferroquadrupolar (AFQ) ordering compound DyB₂C₂. Below T_Q, 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.
