- Abstract
- Ti(1-x)Co(x)O(2-delta) nanobelts were synthesized without using any metal catalysts by metallorganic chemical vapor deposition. The nanobelts consisted of similar to 10-20 nm nanocrystallites, which were dominantly rutile structure. The Ti(0.986)Co(0.014)O(2-delta) nanobelt sample showed a magnetic anisotropy with a high coercive field value (similar to 500 Oe) at room temperature, significantly affected by intrinsic effect. In contrast, the Ti(0.982)Co(0.018)O(2-delta) nanobelt sample revealed isotropic magnetic characteristics due to enhanced Co clustering. A few or several Co clusters per nanobelt were typically observed even in the lightly Co-doped Ti(0.986)Co(0.014)O(2-delta) nanobelts because of the very thin thickness (similar to 20 nm) and high specific surface area of nanobelts.
