Perovskite ABO3 is a kind of the material possessing various interesting electric and magnetic properties, and these properties can be changed dramatically by doping with rare-earth metals. In this paper, nanocrystalline La1–xYxFeO3 and La1-xNdxFeO3 (0 ≤ x ≤ 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 ABO3 affects the structure and magnetic properties of the material. The magnetic properties of La1–xAxFeO3 exhibit clearly in the hysteresis loop M(H), measured at room temperature. The samples show weak ferromagnetic properties, close to the superparamagnetic state at room temperature.
