Ferromagnetism of Co-doped TiO2(B) nanotubes
Wang, X. W., Gao, Xueping, Li, G. R., Gao, L., Yan, T. Y., & Zhu, Huai Yong (2007) Ferromagnetism of Co-doped TiO2(B) nanotubes. Applied Physics Letters, 91(14), pp. 143102-1.
The Co-doped titanate nanotubes, synthesized via a hydrothermal reaction, are calcined at 300, 400, and 500 degrees Celsius for 2 h in an argon atmosphere to yield Co-doped TiO2(B) nanotubes and anatase nanotubes with a dark gray color. It is shown that all calcined titania nanotubes have a stronger absorption in visible region, attributed to the formation of oxygen vacancies. The saturation magnetization of all Co-doped titania nanotubes is stronger than that of as-prepared Co-doped titanate nanotubes. In particular, Co-doped TiO2(B) nanotubes calcined at 300 degrees Celsius exhibit the strongest ferromagnetism due to the existence of oxygen vacancies, as confirmed further by electron paramagnetic resonance spectra.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
