Synthesis and magnetic properties of manganite multiple heterostructure nanoribbons.
The fabrication and applications of two-dimensional complex oxide heterostructures have gained great attention. However, the achievement of these materials in one-dimensional form with multiple interfaces is still elusive. Here, we report the growth of manganite CaMn(3)O(6)/CaMn(2)O(4) heterostructure nanoribbons via the use of CaMnO(3) powders as the precursor for the molten-salt process. In contrast with the antiferromagnetism in CaMn(3)O(6) and CaMn(2)O(4) in the bulk, magnetization measurements indicate the coexistence of a ferromagnetic phase with a spin-glass-like component in CaMn(3)O(6)/CaMn(2)O(4) heterostructure nanoribbons. An asymmetric magnetization hysteresis loop observed in the applied magnetic field H≤ 3 T is attributed to the coupling between the antiferromagnetic phase and the ferromagnetic or spin-glass-like phase in CaMn(3)O(6)/CaMn(2)O(4) heterostructure nanoribbons.
