Structural and magnetic properties of Sm2−xMnxO3 nanoparticles

- C-type Sm2−xMnxO3 (0.0 ≤ x ≤0.20) is prepared by sol-gel method.
- A maximum solubility of x = 0.15 is confirmed by X-ray diffraction, Raman and infrared techniques.
- Samples with x > 0.05 exhibit weak ferromagnetic properties; for x ≤ 0.05 antiferromagnetic behaviors is obtained.
- Correlation between magnetic behaviors and structural and microstructural parameters is discussed.
