Description
Summary:In this study, the synthesis and magnetic properties of the rare-earth iron garnets Sm Fe O , Pr Fe O , and Er Fe O (in the form of powders and thin films) are reported. According to the composition, shape, and size of particles, the optimal precipitant for the synthesis of Sm Fe O , Pr Fe O , and Er Fe O films is an aqueous solution. The parameters for the synthesis of powders and films of the rare-earth iron garnets with micro- and nano-particles have been investigated and selected. The magnetic properties of these materials were studied; field dependencies of the magnetic moment (hysteresis loops) of nanostructured powders of iron garnets of samarium, praseodymium, and erbium in the range of +20 kOe to -20 kOe were obtained. The structural features of the Al O substrate on which the films were formed are also shown.
