Microwave impedance measurements indicate a nonlinear absorption anomaly in single‐walled carbon nanotubes at low temperatures (below 20 K). We investigate the nature of the anomaly using a time resolved microwave impedance measurement technique. It proves that the anomaly has an extremely slow, a few hundred second long dynamics. This strongly suggests that the anomaly is not caused by an intrinsic electronic effect and that it is rather due to a slow heat exchange between the sample and the…
