Ferromagnetism in the two-dimensional periodic Anderson model
Using the constrained-path Monte Carlo method, we studied the magnetic properties of the two-dimensional periodic Anderson model for electron fillings between 1/4 and 1/2. We also derived two effective low-energy theories to assist in interpreting the numerical results. For 1/4 filling, we found that the system can be a Mott or a charge-transfer insulator, depending on the relative values of th...
متن کاملFerromagnetism in the Periodic Anderson Model
We compare different approximation schemes for investigating ferromagnetism in the periodic Anderson model. The use of several approximations allows for a detailed analysis of the implications of the respective methods, and also of the mechanisms driving the ferromagnetic transition. For the Kondo limit, our results confirm a previously proposed mechanism leading to ferromagnetic order, namely ...
متن کاملThe two - dimensional Anderson model of localization
We examine the localization properties of the 2D Anderson Hamiltonian with oo-diagonal disorder. Investigating the behavior of the participation numbers of eigenstates as well as studying their multifractal properties, we nd states in the center of the band which show critical behavior up to the system size N = 200200 considered. This result is connrmed by an independent analysis of the localiz...
متن کاملFerromagnetism and Kondo insulator behavior in the disordered periodic Anderson model.
The effect of binary alloy disorder on the ferromagnetic phases of f-electron materials is studied within the periodic Anderson model. We find that disorder in the conduction band can drastically enhance the Curie temperature T{c} due to an increase of the local f moment. The effect may be explained qualitatively and even quantitatively by a simple theoretical ansatz. The emergence of an alloy ...
