The Frontiers of Geometrically Frustrated Magnetic Materials (#430)

The phenomena of geometrically frustrated magnetism (GFM) has held the interest of the solid state chemistry community for decades. Many of these materials are composed of either triangular or square motifs of transition metal or rare earth magnetic ions in a lattice topology which inhibits conventional magnetic ordering at low temperatures. As a result, exotic magnetic states tend to form at low temperatures, such as spin liquids, monopole formation in solids, or complex magnetic ordering. GFM has also led to practical modern applications and technologically relevant devices, such as multiferroics and high temperature superconductors. The past few years in particular have been marked by a plethora of new frustrated materials synthesized by solid state chemists which are only now being understood, including new pyrochlore materials, perovskite compounds, spinels, triangular antiferromagnets, and molecular magnets. GFM is a very rapidly changing field, with exciting developments in spin-ice candidates, high-pressure solid state synthesis techniques, complex magnetic ordering in multiferroics, and exotic magnetic ground states in low-dimensional compounds. Emphasis in this symposium will be placed on new materials and new synthesis techniques, but new characterization techniques will also be welcomed.
