Abstract
⺠We studied electronic and structural properties of bulk goethite and Al-rich goethite. ⺠The goethite is well described with the GGA + U level using the Ueff = 6 eV value. ⺠The Al-rich goethite model has different magnetic structures with similar energies. ⺠The isomorphic substitution of Fe by Al atom in goethite results in a lattice contraction.
