Abstract
Quantum interference effects in the induced currents in metallic LaB6 are investigated in pulsed magnetic fields extending to 60 T and to te mperatures 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 effect s of phonons to be considered within the Boltzmann transport equation.
