概要
- 論文の詳細を見る
ESR and ^1H NMR investigations were performed on iodine-doped HBC nanotubes to understand the low-temperature electronic states and carrier dynamics. Using ESR measurements, we clarified that the charged carriers induced by iodine-doping possess spins, and we found two kinds of spin species with different doping levels. The ESR results indicate the itinerant features down to 170 K. The ^1H T^<-1>_1 for the heavy-iodine-doped HBC nanotubes follows T^<0.5> and exhibits a characteristic frequency dependence. We propose that the spin excitation propagates along the one-dimensional helical chain.
