An ultrafine-particle plasma consisting of electrons, positive K + ions, and large negative C60- ions is produced by introducing "Buckminsterfullerene, C60" particles into a low-temperature (≃0.2 eV) potassium plasma column confined by a strong axial magnetic field. With an increase in the C60 - fraction, the electron shielding decreases, yielding clear effects on plasma collective phenomena, which are demonstrated for low-frequency electrostatic plasma-wave propagations and instabilities. This plasma might be useful for producing new C60-based materials.
