Dear users in Ifeffit forum, I'm working at a cathode material represented by xLi2MnO3.(1-x)LiMO2 (M = Mn, Ni, and Co). This material can be described as a solid solution between Li2MnO3 and LiMO2. The main phase is the LiMO2 (M = Mn, Ni, and Co), which shows a trigonal crystal structure (R-3m). The integrated phase is the Li2MnO3, which exhibits a monoclinic structure (C2/m). What would be the right way to perform the EXAFS fitting using Artemis for the multi-phase materials ? I was thinking creating two crystal structure set using ATOMS, and perform feff calculation for each, and then choose scattering path from each atom set. I wonder whether this is an appropriate approach ? and how can I apply the ratio of each phase (let's say x is 0.6) in the fitting process ? Thank you in advance ! Kind Regards Taehoon
