Geometrically frustrated magnetic materialsBasis of a presentation given at Materials Discussion No. 3, 26–29 September, 2000, University of Cambridge, UK.

The current state of efforts to understand the phenomenon of geometric magnetic frustration is described in the context of several key materials. All are transition metal oxides which crystallize with magnetic lattices which are geometrically or topologically prone to frustration such as those based on triangles or tetrahedra which share corners, edges or faces. These include the anhydrous alums, jarosites, pyrochlores, spinels, …
