Low Temperature Magnetic Properties of Layered Compounds: NaLnTiO4 (Ln: Sm, Eu, Gd, Tb, Dy, Ho and Er).
2008
Abstract A series of orthorhombic NaLnTiO 4 (Ln = lanthanides) has been synthesized and characterized. These compounds all crystallize in A-site ordered n = 1 Ruddlesden–Popper phase (A n +1 B n O 3 n +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.
