Antiferromagnetic ordering of itinerant systems in modified mean-field theory
This is an analysis of the itinerant model for antiferromagnetism, in which is included both on-site and inter-site electron correlations. We also consider the band degeneration, which brings into the Hamiltonian the on-site exchange interactions. The Green function technique is used and the coherent potential approximation (CPA) decoupling for the on-site Coulomb repulsion. This decoupling com...
متن کاملSHORT RANGE ANTIFERROMAGNETIC ORDERING IN FLUORIDE GLASSES ''PbMnFeF7 AND ''Pb2MnFeF9''
Neutron diffraction and EXAFS experiments have been made on fluoride glasses "PbMnFeF.," and "Pb^MnFeFg" to provide informations about the magnetic short range order of pairs M-M (M = Mn"", Fe3) and the local environment of Mn and Fe3. The magnetic correlation function shows in both glasses prevailing strong antiferromagnetic first neighbour interaction at 3.6 A and two ferromagnetic interactio...
متن کاملAntiferromagnetic spatial ordering in a quenched one-dimensional spinor gas.
We have experimentally observed the emergence of spontaneous antiferromagnetic spatial order in a sodium spinor Bose-Einstein condensate that was quenched through a magnetic phase transition. For negative values of the quadratic Zeeman shift, a gas initially prepared in the F=1, m(F)=0 state collapsed into a dynamically evolving superposition of all three spin projections, m(F)=0, ±1. The quenc...
متن کاملAntiferromagnetic ordering in the Kondo lattice system Yb2Fe3Si5
Compounds belonging to the R2Fe3Si5 series exhibit unusual superconducting and magnetic properties. Although a number of studies have been made on the first reentrant antiferromagnet superconductor Tm2Fe3Si5, the physical properties of Yb2Fe3Si5 are largely unexplored. In this work, we attempt to provide a comprehensive study of bulk properties such as, resistivity, susceptibility and heat-capa...
متن کاملThree-Dimensional Ordering in Weakly Coupled Antiferromagnetic Ladders and Chains
A theoretical description is presented for low-temperature magnetic-field induced threedimensional (3D) ordering transitions in strongly anisotropic quantum antiferromagnets, consisting of weakly coupled antiferromagnetic spin-1/2 chains and ladders. First, effective continuum field theories are derived for the one-dimensional subsystems. Then the Luttinger parameters, which determine the low-t...
