Magnetic Correlations of Ba3MTi2O9 with M = Ru, Rh and Ir.
The triangular spin geometry has been under intense investigation to study the phenomena of spin frustration, primarily on the 3d transition metal-oxides. Recent studies of the S = 1/2 Ba3CuSb2O9 [1], and in the S = 1 Ba3NiSb2O9 materials [2], have attracted great attraction due to their spin frustration. Studying transition metals from the 4d and 5d series introduces an enhanced spin-orbit coupling interaction into the study of magnetism. Here we plan a study magnetic excitations of a series of Ba3MTi2O9 M = Ru (4d S = 1), Rh (4d S = ½) and Ir (5d S = ½) materials in which the spin-orbit interaction will play a prominent role in the magnetism.
