Magnetic Order and Charge Disproportionation in a Spin-ice type Kondo Lattice Model: Large Scale Monte Carlo Study
摘要：
采用蒙特卡罗模拟方法，利用多项式展开技术，得到了自旋冰型近藤晶格模型的相图，该模型可能与金属烧绿石氧化物有关.我们确定了一个新的32-亚晶格磁相伴随的电荷双折射，以及其他阶段，如两进两出和全进/全出的订单。自旋和电荷模式可以通过外部磁场切换到一个不同的伴随着半磁化平台。
英文摘要：
Phase diagram of a spin-ice type Kondo lattice model, potentially relevant to metallic pyrochlore oxides, is obtained by the Monte Carlo simulation implementing the polynomial expansion technique up to the system size with 2048 sites. We identified a new 32-sublattice magnetic phase with concomitant charge disproportionation, along with other phases such as two-in two-out and all-in/all-out orders. The spin and charge pattern can be switched by external magnetic field to a different one accompanied by a half magnetization plateau.
