Coexistence of s-Wave Superconductivity and Antiferromagnetism
We study the phase diagram of a new model that exhibits a first order transition between s-wave superconducting and antiferromagnetic phases. The model, a generalized... -
Theoretical and experimental study of the magnetic properties of transition m...
This work aims to contribute to the study of magnetism in insulating oxides of the type AB_2O _6 (A = Fe, Co, Ni, Ta = B, Sb). These compounds crystallize in a... -
New quantum spin states induced by magnetic frustration on the kagome lattice
Magnetic frustration helps destabilizing conventional Néel order at T = 0 in dimensions 2, and therefore allows the emergence of new original quantum phases. The S=1/2... -

NMR study of phase diagram and electronic correlations in Iron based supercon...
The discovery in 2008 of superconductivity at a rather high temperature in the iron pnictides (Tc,max = 56K) has revived the fundamental questions about the existence... -

Spin dimer and electronic band structure analyses of the ferromagnetism versu...
On the basis of spin dimer analysis and density functional theory electronic band structure calculations, we examined why the magnetic ground state of SeCuO3 is... -
Conjugate orders in the antiferromagnetic state of rare-earth cubic compounds
Les composés cubiques à base de terres rares sont un terrain favorable à l'expression de degrés de liberté alternatifs, liés à la dégénérescence d'orbite et/ou aux...
