Abstract: A multi-frequency electron spin resonance (ESR) study provides evidence for the occurrence of low-temperature ferromagnetic/spin-glass behavior in aligned arrays of sub-nanometer single-walled carbon nanotubes confined in zeolite nanochannels, owing to sp(2)-type non-bonding carbon-associated localized states with density of approximate to 3 x 10(19)/g. Features related to the much anticipated conduction ESR are not detected. In the paramagnetic phase, the ESR linewidth is found to be weakly dependent on microwave frequency. Copyright (C) EPLA, 2010
