Figure 2

(Color Online) Relative energies obtained with FNDMC (blue) and LDA+U (orange) calculations of \(\hbox{LaMnO}_3\) with (a) antisite defect and (b) oxygen vacancy as a function of the total magnetization. The lowest data point is set to zero. LDA+U reproduces the defect magnetization (i.e., energy minima) of FNDMC.
