MAGNETIC ORDERING AND ELECTRONIC STRUCTURE OF CeAl2
CeAl2 has attracted considerable attention because of its unusual properties including a proposed competition between Kondo compensation and anti-ferromagnetic spin-density wave ordering observed at low temperatures. Here we present results of a self-consistent spin-polarized LMTO band study of CeA^. In its paramagnetic state the Ce-f band is about 1 eV wide and, although principally above Ej.,...
متن کاملElectronic-structure-driven magnetic ordering in a Kondo semiconductor CeOs2Al10.
We report the anisotropic changes in the electronic structure of a Kondo semiconductor CeOs(2)Al(10) across an anomalous antiferromagnetic ordering temperature (T(0)) of 29 K, using optical conductivity spectra. The spectra along the a and c axes indicate that an energy gap due to the hybridization between conduction bands and nearly local 4f states, namely the c-f hybridization gap, emerges fr...
متن کاملEffect of nematic ordering on electronic structure of FeSe
Electronically driven nematic order is often considered as an essential ingredient of high-temperature superconductivity. Its elusive nature in iron-based superconductors resulted in a controversy not only as regards its origin but also as to the degree of its influence on the electronic structure even in the simplest representative material FeSe. Here we utilized angle-resolved photoemission s...

متن کاملTuning fulleride electronic structure and molecular ordering via variable layer index.
C60 fullerides are uniquely flexible molecular materials that exhibit a rich variety of behaviour, including superconductivity and magnetism in bulk compounds, novel electronic and orientational phases in thin films and quantum transport in a single-C60 transistor. The complexity of fulleride properties stems from the existence of many competing interactions, such as electron-electron correlati...
