Electronic and magnetic properties of C₆₀ thin films under ambient conditions: A multitechnique study

The magnetic and electronic properties of thin C₆₀ films (film thickness ⩾ P4 ML) grown by sublimation in vacuum on oxidized Si, Au, highly oriented pyrolytic graphite and glass, and subsequently exposed to ambient conditions, are investigated by using a multitechnique approach. The films exhibit a...
