摘要：

Frustration denotes the inability of a system to satisfy all pairwise interactions and enables a large variety of fascinating ground states that depend on the very details of the interactions involved. The focus will be on neutron scattering studies of spinel compounds AB(2)X(4). It is well known that the B-site ions form a pyrochlore lattice with inherent strong geometric frustration (GF). Among these compounds, heavy fermion-like behaviour of LiV2O4 and new kinds of magnetoelastic coupling phenomena in chromate spinels will be considered. Recently, also the A-site spinels has been shown to be subject to strong frustration effects, not only for the spin sector but also for the orbital and structural degrees of freedom. Corresponding ordering phenomena in MAl2O4 (M=Mn, Fe, Co) will be discussed.
