Band Jahn-Teller Effect in LaCd
スポンサーリンク
概要
- 論文の詳細を見る
The bandstructures of LaCd were calculated by the KKR method and the local-spin-density approximation for both the CsCl and the tetragonal structures. Fromthese bandstructures, we find that the band Jahn-Teller effect can cause the cubic-to-tetragonal lattice transformation, that the important factor in this effect is the atomicshifts from the atomic positions of the CsCl structure to the ones of the body-centered-tetragonal structure rather than the distortion along tl'xe c-axis and that notonly d electrons of La but also p electrons of Cd contribute to this effect.
