Figure 1From: Study of the oxygen vacancy influence on magnetic properties of Fe- and Co-doped SnO2 diluted alloysTotal energy vs. magnetic moment per cell. For (a) Sn0.96Fe0.04O2, (b) Sn0.96Fe0.04O1.98(VO)0.02, (c) Sn0.96Co0.04O2, and (d) Sn0.96Co0.04O1.98(VO)0.02. The total energy of the high-spin ground state is set to zero.Back to article page
