Summary: In this paper, ordered porous In2O3 films were prepared on ordered porous Al2O3 thin films by magnetron sputtering. The film exhibits large room-temperature ferromagnetism and magnetic anisotropy. In addition, the research shows that the room-temperature ferromagnetism of the ordered porous In2O3 films is mainly influenced by the oxygen vacancies.

Summary: Ordered porous indium oxide thin films with higher ferromagnetism were prepared using the direct current magnetron sputtering method. The room-temperature ferromagnetic properties of the films were mainly due to the presence of oxygen vacancies. A composite thin-film resistive-magnetization switching device based on In2O3 was successfully developed, showing stable electrical and magnetic control characteristics. This research opens the possibility for the application of In2O3 in spintronic devices.

Summary: Two-dimensional VSe2 and V1-xFexSe2 nanosheets were synthesized using a high-temperature organic solution method, with tunable thickness and room-temperature ferromagnetism. The enhancement of magnetization in V0.8Fe0.2Se2 nanosheets is attributed to the coupling interaction of 3d orbits between V and Fe atoms, showing 5 times higher coercivity and magnetization compared to pure VSe2 nanosheets.

Summary: Fe-doped LiNbO3 thin films were successfully deposited on Si (111) substrates by RF magnetron sputtering technique. XAS analysis revealed the incorporation of Fe ions into the LiNbO3 lattice with mixed-valent state. SQUID results showed that the films exhibited room temperature ferromagnetism, with maximum magnetic moment at 7 at% Fe-doped concentration. The room temperature ferromagnetism observed in Fe-doped LiNbO3 films can be attributed to super-exchange and double-exchange interactions mediated by oxygen ions.

Summary: In this study, Ga and Ti co-doped In2O3 (IGTO) films were designed as flexible and transparent electrodes for thin film heaters (TFHs) and flexible touch screen panels (FTSPs) in automobiles. The IGTO electrodes deposited on cyclic olefin copolymer (COP) showed good properties in terms of sheet resistance, transmittance, and surface roughness. Moreover, the IGTO/COP samples exhibited mechanical flexibility and stable touch sensitivity. These findings suggest that IGTO/COP is a promising flexible and transparent electrode for curved TFHs and FTSPs in next-generation automobiles.

Summary: Despite efforts to find room temperature ferromagnetic 2D materials, only a few have been synthesized. A recent study confirmed room temperature ferromagnetism in a multilayer structure. However, calculations showed an antiferromagnetic ground state in the monolayer and bilayer systems. Further investigation revealed that hydrogen-induced ferromagnetism was possible. The resulting systems showed a ferromagnetic ground state and optically transparent behavior.

Summary: The study demonstrates the high infrared transmittance (>50% at 4-mu m-wavelength), low sheet resistance (<200 Omega square(-1) at room temperature), and high shielding effectiveness (similar to 16.2 dB at 10 GHz for the X-band) of 20-90-nm-thick Sn-doped In2O3 films deposited on an (0001)-oriented Al2O3 substrate. The multifunctional Sn-doped In2O3 films on Al2O3 substrates have potential applications in military, circuitry, windows, sensors, and transparent solar cells.

Summary: In this study, pure and Fe-doped indium oxide nanostructured thin films were deposited by pulsed laser on quartz substrates. The films exhibit polycrystalline structures with cubic bixbyite geometry, arranged in semi-regular patterns with low surface roughness. Fe doping leads to a decrease in band gap and optical transmittance, as well as an increase in resistivity and a decrease in carrier concentration and mobility. The films exhibit n-type semiconducting behavior and follow the Mott-VRH conduction model at lower temperatures.
