Abstract:
Unusually narrow electron spin resonance lines can give birth to spectacular and interesting phenomena. We use here very pure lithium metal colloids created in electron-irradiated LiF, giving rise to a very narrow Li metal line. In these samples, three interesting phenomena are discussed and interpreted: signal saturation in particularly good conditions; oscillations appearing on strongly overmodulated lines; signal bistability, when the signal shape seems to depend on the sample magnetic history.
