Abstract
A synergistic approach combining the experimental photoelectron spectroscopy and theoretical electronic structure studies is used to demonstrate the existence of magnetic isomers as well as configurations having comparable binding energies, identical spins, and yet differing in the distribution of local moments (called isomags). Our studies carried out on Mn5O and Mn6O clusters show that while the O atom occupies either bridge or hollow site with a binding energy of 6.88eV in Mn5, it prefers a hollow site with a binding energy of 7.18eV in Mn6 clusters. Mn5O is shown to possess two magnetic isomers with total spins of 13 and 5μB that contain three and five isomags, respectively. Mn6O possesses three isomers, two with moments of 8 and 2μBand a nonmagnetic. It is shown that the isomags, although undetected in magnetic experiments, can be identified via their electronic structure in experimental photoelectron spectra.
