Neutron scattering investigation of the spin correlations in frustrated spinels
, 2017 Spinels of the chemical formula AB2X4 are important systems in the study of frustrated magnetism. The A and B sites of spinels constitute diamond and pyrochlore lattices, respectively, whose special geometries can give rise to many exotic phenomena.
