Abstract
We present model calculations for alkaline-earth and rare-earth metal-doped C-60 solids. We have calculated bulk properties such as cohesive energy, lattice constant and bulk modulus for MnC60 (M = Ba, Sr, Ca and Yb, Sm) for n <= 6. The total cohesive energy was calculated by taking into account van der Waals and screened Coulomb interactions. We found that full charge transfer from cation to anion is favored for all MnC60 systems. The bulk properties for these systems are in good agreement with other calculations/experimental observations.
