Universal magnetic structure of the half-magnetization phase in Cr-based spinels
Abstract
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 CdCr2O4. The magnetic structure has a cubic P4332 symmetry, which is the same as that observed in HgCr2O4. This suggests that there is a universal field induced spin-lattice coupling mechanism at work in the Cr-based spinels.
