Abstract: The structural and magnetic properties of magnetic iron-oxide nanoparticles obtained by a modified codeposition method with reduced concentrations of metal cations in the initial solution are studied, and an approach with ultrasonic stirring of the solution is developed. It is found that ultrasonic synthesis leads to the formation of nanoparticles with a high content of the crystalline phase compared to particles obtained using the classical approach with mechanical stirring, which produces nanoparticles of a smaller size and with a larger volume fraction of the X-ray amorphous phase. Nanoparticles obtained by the modified method have a high saturation magnetization, and therefore the approach can be adapted to obtain magnetic nanocomposites by introducing nanoparticles of a different nature into the solution, which will act as a nucleus for growth of the magnetic phase. |
