Fig. 2: Energy differences with respect to the ground state of La2TiFeO6 and La2VCuO6 ordered phases with different magnetic configurations.

La2TiFeO6 and La2VCuO6 energy per formula unit of the different states investigated for rock-salt and layered B-site ordering, for bulk phase and for phases strained to SrTiO3 and LaAlO3(100) oriented substrates. Charge transfer and non-charge transfer states are shown for La2TiFeO6 while G-type and non-magnetic states are shown for La2VCuO6.
