Using an elastic neutron scattering technique under a pulsed magnetic field up to 30 T, we determined the magnetic structure in the half-magnetization plateau phase in the spinel CdCr$$_2$$O$$_4$$. The magnetic structure has a cubic $$P$$4$$_3$$32 symmetry, which is the same as that observed in HgCr$$_2$$O$$_4$$. This suggests that despite their different zero-field ground states a universal field induced spin-lattice coupling mechanism is at work in the Cr-based spinels.
