Abstract

The crystal structure, magnetic, and transport properties of (Tb _{1 - x}Na_x)MnO₃ (0 ≤ x ≤ 0.3) perovskites prepared by solid-state reaction were investigated. According to powder X-ray diffraction (XRD), the compounds were found to be of orthorhombic crystal structure with a space group Pbnm. The (Tb_{1 - x}Na_x) MnO₃ system shows a magnetic transition around 10, 20, and 30 K for x = 0, 0.15, and 0.3, respectively, at a magnetic field of 1000 Oe. Both magnitude and the temperature position of the peak increase with increasing Na content. This behavior points to enhancement of the ferromagnetic interactions. Moreover, a decrease in activation energy from 62 meV (x = 0) to 39 meV (x = 0.3) was found. This means that Na substitution decreases the activation energy and resistivity in the parent TbMnO₃.
