Abstract

The double rearth elements La1βˆ’π‘₯Ndπ‘₯FeO3 (0≀π‘₯≀0.5) nanosized powders with orthorhombic structure were prepared by sol-gel method. The particle size of the La1βˆ’π‘₯Ndπ‘₯FeO3 powder is about 20 nm. The doping of the second rearth element in the A position of the compound ABO3 influenced the crystalline structure and magnetic property of the samples. The 𝑀(𝐻) dependence shows that the nanosized La1βˆ’π‘₯Ndπ‘₯FeO3 samples exhibit ferromagnetic behavior in the room temperature and the 𝑀(𝐻) curves are well fitted by Langevin functions.
