The N el temperatures of the ortho ferrite perovskites LnFeO3 are listed below Hint These are all orthorhombic perovskites SYC Lecture 4 p25 of the pdf how would you expect this distortion to effect the Fe 0 Fe angle and how will this be effected by changing the tolerance factor Compound N el Temperature K LaFeO3 743 PrFeO3 707 NdFeO3 SmFeO3 EuFeO3 GdFeO3 689 673 662 658 n terms of superexchange explain why FeF3 has a significantly lower N el temperature 200 K than LaFeO3
