MVPACK: A package to calculate energy levels and magnetic properties of high nuclearity mixed valence clusters

We present a FORTRAN code based on a new powerful and efficient computational approach to solve the double exchange problem for high-nuclearity MV clusters containing arbitrary number of localized spins and itinerant electrons. We also report some examples in order to show the possibilities of the program. © 2009 Wiley Periodicals, Inc. J Comput Chem, 2010
