Abstract
Gd2O3 nanoparticles thin films obtain through the spin coating techniques deposited on substrate of p-Si(100) . The structural properties of the thin film were measured by X-ray diffraction technology (XRD) to know the crystal structure and the effect of the difference of different annealing temperatures on the crystal growth of these samples, and the scanning electron microscopy examinations (SEM) and the magnetic properties were studied using the Vibrating Sample Magnetometer(VSM) of Various annealing temperatures (500,600,700,800) ̊C. The results of the X-ray diffraction showed that all the prepared membranes have a multi-crystalline structure with different diffraction values and directions and the Gd2O3 thin film were of the cubic type and it was noted that by increasing the annealing temperature we get the best crystalline development and the results of SEM showed that the shape of the deposited nanoparticles was spherical, and we note an increase in the saturation magnetization (MS) about (0.1421 - 0.1811) emu / g with increased of annealing temperature.
