被引用回数:28 パーセンタイル:77.3(Physics, Multidisciplinary)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 CdCrO. The magnetic structure has a cubic 432 symmetry, which is the same as that observed in HgCrO. 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.
