摘要：

A series 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(3n+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. (c) 2006 Elsevier B.V. All rights reserved.
