Neutron scattering experiments have revealed a field-induced antiferroquadrupolar order parameter in the Pr-based heavy-fermion superconductor. We observed the field-induced antiferromagnetic dipole moment with the propagation vector q=(100) for the applied field direction both H‖[110] and [001]. For H‖[110] at, it should be noted that the induced antiferromagnetic moment oforients parallel to the field within our experimental accuracy. This observation is strong evidence that theelectric quadrupole is the primary order parameter for H‖[110]. A mean-field calculation, based onsinglet andexcited triplet with thequadrupolar interaction, reproduces the induced moment direction and its field response. These facts indicate the predominance of-type antiferroquadrupolar interaction in.
