The dc magnetization displays a weak diamagnetic susceptibility of ≈ 10-7 emu/g. ESR measurements reveal a narrow resonance line of low intensity and metallic line shape. The spin susceptibility shows a major Pauli contribution at high temperatures (T&gt;150 K) and an appreciable Curie component at lower temperatures. A marked drop of the spin susceptibility is observed at T&lt;14 K, pointing to the opening of a spin gap at low temperatures. The underlying mechanism is discussed in terms of an electronic instability of the SWNTs or the occurrence of defect-mediated spin magnetism. © 2007 The American Physical Society.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 38</style></notes></record></records></xml>
