TL;DR: It is shown that uniaxial pressure can induce profound changes in the superconductivity of one of the model materials in the field, Sr2RuO4, and demonstrated using explicit calculations how the findings provide strong constraints on theory.
Journal ArticleDOI
Prediction of high T(c) superconductivity in hole-doped LiBC.
TL;DR: In this article, hole doping of LiBC results in Fermi surfaces of B-C $p\ensuremath{\sigma}$ character that couple very strongly to B -C bond stretching modes.
Prediction of High T c Superconductivity in Hole-doped LiBC
TL;DR: Comparison of Li(0.5)BC with MgB2 indicates the former to be a prime candidate for electron-phonon coupled superconductivity at substantially higher temperature than in M gB2.
Journal ArticleDOI
Magnetic properties of BaCdVO ( PO 4 ) 2 : A strongly frustrated spin- 1 2 square lattice close to the quantum critical regime
TL;DR: In this paper, magnetization and specific-heat measurements on polycrystalline samples of BaCdVO were performed and it was shown that this compound is a frustrated square lattice with ferromagnetic nearest-neighbor and antiferromagnetic next-nearest neighbor interactions.
Journal ArticleDOI
AFe2As2 (A = Ca, Sr, Ba, Eu) and SrFe2-xTMxAs2 (TM = Mn, Co, Ni): crystal structure, charge doping, magnetism and superconductivity

TL;DR: In this article, the relationship between the crystal structure, charge doping and magnetism in AFe2As2 systems was analyzed using first-principle band structure calculations, and the tetragonal to orthorhombic structural distortion along with the associated magnetic order and anisotropy, the influence of doping on the A site and the Fe site were analyzed.
