Hydrothermal synthesis of DyMn2O5 nanorods and their magnetic properties

• DyMn2O5 nanorods have been synthesized via hydrothermal route.
• DyMn2O5 showed UV excitation and near band edge (NBE) emission.
• Crystalline DyMn2O5 showed a weak ferromagnetic ordering.
• The ferromagnetic transition could be ascribed to core/shell structure.

Highly pure DyMn2O5 nanorods have been synthesized via hydrothermal route. FT-IR and Raman patterns were employed to determine DyMn2O5. PLE and PL spectra of DyMn2O5 showed UV excitation and near band edge (NBE) emission. Magnetic measurement indicated the crystalline DyMn2O5 showed a weak ferromagnetic ordering due to incomplete spin compensation on the surface. The ferromagnetic transition could be explained by an antiferromagnetic core and a ferromagnetic surface.
