Reports Outline Titanium Dioxide Nanotechnology Study Results from T.S. Wu et al

June 6, 2014

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Nanotechnology. According to news reporting originating from Shijiazhuang, People's Republic of China, by NewsRx correspondents, research stated, "Remarkable room-temperature ferromagnetism was found in porous TiO2 thin films deposited on porous anodic alumina substrates using DC-reactive magnetron sputtering. A physical property measurement system measurement indicates that the out-of-plane saturation magnetization is about 126 emu/cm(3)."

Our news editors obtained a quote from the research, "The magnetization depends on special porous structure and decreases rapidly after air-annealing. These suggest that the origin of ferromagnetism may be due to exchange interactions between singly ionized oxygen vacancies directly (F+-F+), or by mediation of conduction electrons (F+-conduction electrons-F+) in the porous TiO2 thin films."

According to the news editors, the research concluded: "The results reveal that it is a promising candidate for spintronic devices."
