Chemistry, Physics and Technology of Surface| Summary: | Preparation techniques have been developed of magnetic-sensitive nanostructures based on magnetite with incorporated gadolinium ions. Structure and composition of the nanocomposites have been examined by IR-spectroscopy, X-ray analysis and X-ray photoelectron spectroscopy. Magnetic characteristics have been studied with vibrating sample magnetometer. An amorphous phase of gadolinium hydroxide has been shown to be formed on surfaces of nanosized magnetite particles. When the samples are heat treated at 800–1000°С, a crystal phase of ferrite GdFeO3is formed. |
