Single-crystal x-ray diffraction experiments on the geometrically frustrated magnet CdCr2O4 have been carried out under pulsed magnetic fields up to 31 T. By applying magnetic fields, CdCr 2O4 exhibits a magnetization plateau which is one-half of the saturated magnetization above 28 T, and it is expected that a structural transition from a tetragonal to a rhombohedral or cubic structure occurs simultaneously through a so-called "spin Jahn-Teller" mechanism. Our diffraction experiments confirmed that a sharp structural transition occurs at 28 T and that the 440 reflection is a single peak, suggesting that the crystal structure of the high-field plateau phase is cubic.
