Abstract

The ferromagnetic Fe-In2O3 nanocomposite thin film has been synthesized by the thermite Fe2O3 + In → Fe-In2O3 reaction. The transmittance (400 – 1100 nm) was measured at temperatures from 320 to 5 K. It was found that the transmittance increases when temperature decreases. For wavelength 600, 700, 800, 900 and 1000 nm maximum change of transmittance was ~ 3.2, 4.2, 4.8, 5.1 and 5.4 %, respectively. From transmittance spectra, spin glass-like behavior was observed near ~ 36 K and confirmed by magnetization measurements. The Verwey transition was identified at ~ 127 K by magnetization measurements. We have shown direct relationship between transmittance and magnetization of nanocomposite Fe – In2O3 thin film near ~ 36 K and give proposed possible mechanism this phenomena.

21. Structural and Magnetic Characteristics of Nanogranular Co–Al2O3Single- and Multilayer Films Formed by the Solid-State Synthesis

Author

Volochaev, M., Komogortsev, S., Myagkov, V., Bykova, L., Zhigalov, V., Shestakov, N., Velikanov, D., Smolyakov, D., Luk’yanenko, A., Rachek, V., Loginov, Yu., Tambasov, I., and Matsynin, A.

Abstract

The results of structural and magnetic investigations of nanogranular Co–Al2O3films formed from Co3O4/Al thin-film layered structures upon vacuum annealing are reported. The Co3O4/Al films have been obtained by sequential reactive magnetron sputtering of a metallic cobalt target in a medium consisting of the Ar + O2gas mixture and magnetron sputtering of an aluminum target in the pure argon atmosphere. It is shown that such a technique makes it possible to obtain nanogranular Co–Al2O3single- and multilayer thin films with a well-controlled size of magnetic grains and their distribution over the film thickness.

Abstract

We have successfully synthesized ferromagnetic Fe-In2O3 nanocomposite thin films for the first time using the thermite reaction Fe2O3+In=In2O3+Fe. The initial In/Fe2O3 bilayers were obtained by the deposition of In layers on α-Fe2O3 films. The reaction occurs in a self-propagating mode in a homogeneous thermal film plane field at heating rates above 20K/s and at temperatures above initiation temperature Tin~180°С. At heating rates lower than 20K/s the mixing of the In and Fe2O3 layers occurs across the whole In/Fe2O3 interface and the synthesis of the ferromagnetic α-Fe phase starts above the initiation temperature Tin=180°С. X-ray diffraction, X-ray photoelectron spectroscopy, Mossbauer spectroscopy, transmission electron microscopy and magnetic measurements were used for phase identification and microstructure observation of the synthesized Fe-In2O3 samples. The reaction products contain (110) textured α-Fe nanocrystals with a diameter around 100nm and surrounded by an In2O3 matrix. These results enable new efficient low-temperature methods for synthesizing ferromagnetic nanocomposite films containing ferromagnetic nanoclusters embedded in transparent conducting oxides.
