All atomic magnetic moments in YBaFe₂O₅ lie along the y axis. Based on Figure 11.3 (in which two chemical unit cells are drawn on the left, four on the right) and information in the text, sketch with arrows the Fe magnetic moments in the smallest magnetic-unit-cell parallelepipeds of charge-ordered and valence-mixed YBaFe₂O₅.
