Title: Local Magnetic Properties of Geometrically Frustrated Magnets
Speaker: Dr. Sarah Dunsiger
Institute: Los Alamos National Laboratory Condensed Matter & Thermal Physics Group Los Alamos, New Mexico
Location: HSC-1A5
Description:
Since Anderson considered the problem of antiferromagnetic ordering on the pyrochlore lattice in 1956, there has been a great deal of interest in systems where the magnetic ions occupy the vertices of edge or corner sharing triangular units. In these cases the natural magnetic coupling between ions is said to be geometrically frustrated. The pyrochlore transition metal oxides, of general formula A2
