Abstract

We have observed a new de Haas-van Alphen (dHvA) oscillation in CeRu ₂Si₂ of frequency 5.36 × 10⁷ Oe and cyclotron effective mass 120m₀ for magnetic fields along the [100] direction. The new dHvA frequency is thought to arise from the heavy electrons of the large hole surface centered at the Z point which is predicted by the band structure calculations.
