TLDR

Abstract: 
The magnetic susceptibility (χ) of polycrystalline samples of RGa2, R=Ce, Pr, Nd, Gd, Tb, Dy, Ho, and Er, has been measured at low field, from 1.5 K to 300 K. The magnetization of these samples also has been measured up to 80 kOe at low temperatures. Antiferromagnetic behavior was observed for all the samples with Neel temperatures (TN) ranging from about 4.1 K for CeGa2 to about 14.8 K for TbGa2. Curie‐Weiss fits to the high‐temperature χ (T) data led to effective moments in good agreement with those expected for R3+ ions. The paramagnetic Weiss temperatures cannot be reconciled with the de Gennes theory based on free electron coupling of the R spins via the RKKY interaction. Electrical resistivity of selected polycrystalline samples has been measured, and the effects of spin‐disorder scattering observed below TN. CeGa2 shows no evidence of Kondo behavior. Magnetization measurements for the polycrystalline samples show metamagnetic phase transitions when the antiferromagnetic R‐R interactions are overcom...

- 01 Nov 1982 - 
TL;DR: In this paper, the transition from the antiferromagnetic structure to the ferromagnetic one, when the field is applied along c, occurs through an intermediate phase, which is very well accounted for using a simple Ising-like model which takes into account first and second nearest neighbours exchange interactions in the hexagonal layers.

TL;DR: In this paper, the Hartree-Forck approximation is used to calculate energy bands and Fermi Surfaces for semiconductor crystals. But the results of the energy bands do not cover the entire crystal lattice.

Kondo Lattice: Real-Space Renormalization-Group Approach

R. Jullien, +2 more
- 20 Jun 1977 - 
TL;DR: In this paper, a one-dimensional analog of the Kondo lattice is studied by a renormalization-group technique, and it is shown that the system undergoes a second-order crossover transition from an antiferromagnetic state to a Kondo-like state at zero temperature as the spin-conduction-electron coupling is increased.
