Magnetic properties in transition-metal-doped gold clusters:: M@Au6 (M=Ti,V,Cr) -: art. no. 253401

The electronic structure and magnetic properties in a series of transition-metal-doped Au clusters, MAu6- (M=Ti,V,Cr), are investigated experimentally using photoelectron spectroscopy (PES) and density functional calculations. PES features due to the impurity atoms and the Au-6 host are clearly observed. It is found that all the MAu6- and MAu6 clusters possess a planar structure, in which the transition metal atom is located in the center of an Au-6 ring and carries large magnetic moments (2, 3, and 4 mu(B) for MAu6, M=Ti, V, and Cr, respectively).
