Neutron-diffraction experiments on single-crystalline Tb11B2C2 were carried out under magnetic fields applied along the [0 1 0] direction. The application of magnetic fields results in the appearance of an antiferromagnetic 1 0 0 reflection above 0.5 T. In consequence, the magnetic structure of a field-induced phase of TbB2C2 can be described with the propagation vectors of the dominant k1 = (1 0 0), k2 = (0 1 1/2) and the additive k3 = (0 0 0), k4 = (0 0 1/2). This result indicates that a field-induced antiferroquadrupolar order is realized in TbB2C2.
