High-resolution powder diffractometry is a powerful method to determine the accurate crystal system and crystal structures. Neutron powder diffraction using TOF neutron diffractometer （SuperHRPD） in MLF at J-PARC and X-ray powder diffraction using Debye-Scherrer diffractometer with one-dimensional MYTHEN detector at SPring-8 are introduced. We successfully observed the structural phase transitions accompanied by small crystal distortion in spinel oxide CoV2O4 and its substitution system by combination of these measurements and clarify the nature of the phase transition of CoV2O4.
