Synthesis, structure and magnetic properties of Ti doped La₂MnNiO₆ double perovskite

Abstract

We report sol-gel synthesis, structural characterization and magnetic properties of La₂Mn_1-xTi_xNiO₆ (0 ≤ x ≤ 1.0). Ti doping removed the biphasic structure of La₂MnNiO₆ by suppression of rhombohedral structure and all the Ti containing samples crystallized in monoclinic P2₁/n symmetry. La₂MnNiO₆ exhibits multiple magnetic transitions. The high temperature ferromagnetic transition of La₂MnNiO₆ gradually shifted to lower temperatures with increase in Ti doping. La₂TiNiO₆ (x = 1.0) does not show any long-range magnetic ordering. The suppression of magnetic transition by Ti doping is ascribed to the destruction of Mn⁴⁺—O—Ni²⁺ superexchange interaction. However, the signature of ferromagnetic phase persists up to 70% Ti doping, indicating the robustness of magnetic ordering in La₂MnNiO₆. These results suggest that the addition of Ti⁴⁺ truncates the ferromagnetic Mn⁴⁺—O—Ni²⁺ superexchange path and it likely promotes ferromagnetic cluster formation. The robustness of ferromagnetic state towards Ti substitution compared to the simple perovskite or spinel structure can be attributed to cationic ordering in double perovskite structure. Both the pure and Ti-doped samples exhibit magnetic frustration at lower temperatures due to partial cationic disordering. The absence of long-range ordering in La₂TiNiO₆, unlike La₂TiCoO₆ or Pr₂TiCoO₆, could be related to cationic disordering.
