In this paper, nanocrystalline La<sub>1–<em>x</em></sub>Y<em><sub>x</sub></em>FeO<sub>3</sub> and La<sub>1-<em>x</em></sub>Nd<em><sub>x</sub></em>FeO<sub>3 </sub>(0 ≤ <em>x</em> ≤ 0.3) were prepared by using the high-energy milling method. The X-ray diffraction (XRD) analysis reveals that the doped samples are single-phased with orthorhombic structure. The average size of particles, calculated according to the Scherrer equation, is about 16 nm. The doping of Y and Nd into the A position of ABO<sub>3</sub> affects the structure and magnetic properties of the material. The magnetic properties of La<sub>1–<em>x</em></sub>A<em><sub>x</sub></em>FeO<sub>3</sub> exhibit clearly in the hysteresis loop <em>M</em>(H), measured at room temperature. The samples show weak ferromagnetic properties, close to the superparamagnetic state at room temperature.</p>}, number={1B}, journal={Hue University Journal of Science: Natural Science}, author={Thuy, Nguyen Thi and Nhan, Pham Nguyen Thi Thanh and Le, Le Thi}, year={2020}, month={Jun.}, pages={25-29} }
