本文研究了ffe - 4p12和NdFe - 4p12填充方角铁矿中的de Haas-van Alphen效应和横向磁阻。lafe4p12的费米表面由一个近球形的孔片和一个多连通的孔片组成。用全势线性化增强平面波（FLAPW）带结构计算可以很好地解释这些特征。ndfe4p12的费米表面与lafe4p12相似，只是在dHvA频率上存在交换分裂。由于电子-磁振子相互作用，回旋加速器的有效质量比lafe4p12的有效质量提高了大约两倍。
We have investigated the de Haas-van Alphen (dHvA) effect and the transverse magnetoresistance in filled skutterudite LaFe 4 P 12 and NdFe 4 P 12 . The Fermi surface of LaFe 4 P 12 consists of a nearly spherical hole sheet and a multiply connected one. These features are explained reasonably well by a full potential linearized augmented-plane-wave (FLAPW) band structure calculation. The Fermi surface of NdFe 4 P 12 is similar to those in LaFe 4 P 12 except the exchange splitting in the dHvA frequencies. The cyclotron effective masses are enhanced roughly twice compared to those of LaFe 4 P 12 due to the electron-magnon interaction.
