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 Au6 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 Au6 ring and carries large magnetic moments (2, 3, and 4 _B for MAu6, M _ Ti, V, and Cr, respectively).
