Low temperature magnetic properties of layered compounds : NaLnTiO4 (Ln = Sm, Eu, Gd, Tb, Dy, Ho and Er)

A series of orthorhombic NaLnTiO4 (Ln=lanthanides) has been synthesized and characterized. These compounds all crystallize in A-site ordered n=1 Ruddlesden-Popper phase (An+1BnO3n+1) structure. The weak ferromagnetism with large magnetization has been observed for Ln=Tb and Dy, and non-linear field...

Zusammenfassung:	A series of orthorhombic NaLnTiO4 (Ln=lanthanides) has been synthesized and characterized. These compounds all crystallize in A-site ordered n=1 Ruddlesden-Popper phase (An+1BnO3n+1) structure. The weak ferromagnetism with large magnetization has been observed for Ln=Tb and Dy, and non-linear field dependence of magnetization without hysteresis has been observed for Ln=Er and Ho. By performing the symmetry operations, two possible canted spin arrangements have been proposed.
