摘要：

Quantum interference effects in the induced currents in metallic LaB6 are investigated in pulsed magnetic fields extending to 60 T and to temperatures of up to 70 K. One of the quantum interference frequencies, corresponding to an area in k space equal to the Brillouin zone, has an effective mass precisely equal to zero. The attenuation of this and other frequencies at high temperatures requires the scattering effects of phonons to be considered within the Boltzmann transport equation.
