de Haas-van Alphen Effect in LaB_2C_2
スポンサーリンク
概要
- 論文の詳細を見る
Fermi surfaces of LaB_2C_2 were investigated by the measurement of the de Haas-van Alphen (dHvA) oscillations. The angular dependence of the dHvA frequency indicates the presence of the multiple three-dimensional closed Fermi surfaces, that is, the 5d orbitals in lanthanum strongly hybridize with the 2p orbitals in boron-carbon sheets. The angular dependence of the dHvA frequency coincides very well with that predicted by the band calculations. The branch having the highest frequency larger than cross-section of the 1st Brillouin zone corresponds to the large orbit originating from magnetic breakdown.
