The Stoichiometry of FeSe
A. J. Williams, T. M. McQueen, R. J. Cava
Tetragonal iron selenide, FeSe, the layered parent compound of the recently discovered superconducting arsenide family, has previously been shown to be non magnetic and superconduc…
Metal - Insulator transition in Fe1.01-xCuxSe
A J Williams, T M McQueen, V Ksenofontov +2
Iron Selenide, Fe1.01Se, the layered parent compound of the recently discovered superconducting arsenide family, has previously been shown to be non magnetic and superconducting wi…
The Structural Phase Transition in FeSe (Fe1+dSe)
T. M. McQueen, A. J. Williams, P. W. Stephens +6
In this letter we show that superconducting Fe1.01Se undergoes a structural transition at 90 K from a tetragonal to an orthorhombic phase but that non-superconducting Fe1.03Se does…
Stoichiometry, Spin Fluctuations, and Superconductivity in LaNiPO
T. M. McQueen, T. Klimczuk, A. J. Williams +2
Superconductivity in LaNiPO is disrupted by small (~5%) amounts of non-stoichiometry on the lanthanum site, even though the electronic contribution to the heat capacity increases w…
