Abstract

We discuss the ferromagnetic phase of the planar Kondo lattice model using the bond fermion technique. For sufficiently small Kondo exchange we find a weakly ferromagnetic phase already for the weakly doped Kondo insulator. We present the phase diagram of the model and its quasiparticle band structure in the different phases.

近藤晶格中的铁磁性

摘要

我们讨论使用键费米子技术的平面近藤晶格模型的铁磁相。对于足够小的Kondo交换,我们已经为弱掺杂的Kondo绝缘子找到了弱铁磁相。我们展示了模型的相图及其在不同相中的准粒子能带结构。
