Neutron-diffraction techniques have been used to study the interplay between superconductivity and magnetism in HoNi[sub 2]B[sub 2]C ([ital T][sub [ital c]]=8 K). The experimental results, obtained on [ital single] crystals, show that below approximately 4.7 K, this compound is in a simple antiferromagnetic state that coexists with superconductivity. Between approximately 4.7 and 6 K, an incommensurate modulated magnetic structure has been found. This observation strongly suggests that pair breaking associated with this incommensurate magnetic structure is responsible for the deep minimum in [ital H][sub [ital c]2] and the near-reentrant behavior observed in this compound at approximately 5 K.
