a Fluorite oxides (Dy0.25Er0.25Y0.25Yb0.25)3NbO7; b Perovskite oxides Sr(Ti0.2Y0.2Zr0.2Nb0.2Sn0.2)O3; c fergusonite oxides with monoclinic phase (Nd0.2Sm0.2Gd0.2Er0.2Yb0.2)NbO4; d Pyrochlore oxides Ca1.2Gd0.8Zr0.8Nb0.6Ta0.6O7; e Dislocation density varies with configurational entropy. The error bars represent the standard deviation of calculated dislocation density. The yellow squares mark the area around the dislocations.
