Electronic Structure and Magnetism of Mixed Atomic Clusters

Authors: P. Jena; S. N. Khanna; B. K. Rao; VIRGINIA COMMONWEALTH UNIV RICHMOND DEPT OF PHYSICS
Abstract:
During this project we have studied the magnetic behavior of Ni, V, Rh, Gd, and Mn Clusters, interaction of metal clusters with substrates and hydrogen, iron-carbon clusters, the hydrogen-vacancy complexes and have explained anomalies spectroscopic data on metal cluster anions. Our studies have enabled: (1) an understanding of the magnetic behavior of clusters of conventional ferromagnetic metals Fe, Co, Ni, (2) predicted ferromagnetism in Rh(n) clusters, (3) examined spin canting in Gd(n) clusters, and (4) predicted that clusters of antiferromagnetic solids like Mn are magnetic. We have offered the first explanation of the anomalies in the negative ion spectroscopy of Li(n) clusters and have provided a basic understanding of the Hydrogen-vacancy complexes.
