Exercise: Charge Transfer on Mn3+ • Copy the rcg, rac, ban and plo files of als6ni2x1 to exct1 (or any other name) • Modify the calculation from Ni2+ to Mn3+. • Start by making the rcn-files for Mn 3d4 and Mn 3d5 ground states. Run TTRCN on them and replace the Ni parameters in the rcg-file with the Mn parameters. • Run TTRCG, TTRAC and TTBAN on the Mn files. • Plot the result • Modify exct1.ban in order to calculate • The pure 3d4 ground state • The pure 3d5 ground state • The spectrum of LaMnO3
