In this paper, the nano perovskite La1–xAxFeO3 sample systems (A = Y, Nd), with x = 0, 0.1, 0.3, were successfully fabricated. The doping of rare earth elements Y or Nd causes the perovskite structure to be distorted, leading to the appearance of a covalent mixed state that strongly affects the of the manufactured materials. The sample system shows the magnetic properties close to the superparamagnetic state at room temperature. |
