摘要
The effects of disorder on the geometrically frustrated magnet ZnCr2O4 are examined through magnetic susceptibility and inelastic neutron-scattering measurements on Zn1-x2+Cdx2+Cr2O4. 3% Cd doping destroys the Neel order of the parent compound, replacing it with a frozen phase of spin-correlated nanoclusters. The local spin structure of these nanoclusters endures through the paramagnetic, spin-glass, and Neel phases of the material.
