Unusual magnetic order in Eu$_{10}$Hg$_{55}$ Open
In solid-state compounds, the valence of europium can sometimes be mixed -- which is especially favored in structures with several positions for the europium atoms. In this work, we study the Eu-based intermetallic noncentrosymmetric syste…

Communication—Annealing Strategies for Spray Deposited Precursor Films of p-Type CuCr<sub>1-x</sub>Mg<sub>x</sub>O<sub>2</sub> Open
Annealing of sprayed pure and Mg doped CuCrO 2 thin films by high intensity, short time light irradiation leads to a single delafossite phase at comparatively low temperatures compared with traditional furnace annealing. P-type crystalline…

Oxygen isotope effect on the superfluid density within the d-wave and s-wave pairing channels of YBa₂Cu₄O₈ Open
We report on measurements of the oxygen isotope ($^{16}$O/$^{18}$O) effect (OIE) on the transition temperature $T_{\rm c}$ and the zero-temperature in-plane magnetic penetration depth $λ_{\rm ab}(0)$ in the stoichiometric cuprate supercond…

Unconventional Transport Properties of Reduced Tungsten Oxide WO2.9 Open
The temperature and magnetic field dependence of resistivity in WO2.9 was investigated. The variation of resistivity with temperature displayed unusual features, such as a broad maximum around 230 K and a logarithmic increase of resistivit…

Complementary Response of Static Spin-Stripe Order and Superconductivity to Nonmagnetic Impurities in Cuprates Open
We report muon-spin rotation and neutron-scattering experiments on nonmagnetic Zn impurity effects on the static spin-stripe order and superconductivity of the La214 cuprates. Remarkably, it was found that, for samples with hole doping x≈1…
