The family of pyrochlore complex oxides includes many materials of fundamental or practical interest, such as spin ices and dielectrics. Trump et al. show that flexibility of the pyrochlores’ structure leads to local displacements that explain some

The structural, superconducting, and electronic phase diagram of [Tl4]Tl1−xSnxTe3 is reported. Magnetization and specific heat measurements show bulk superconductivity exists for 0 ≤ x ≤ 0.4. Resistivity measurements indicate a crossover from a

We report the successful crystal growth of a previously unknown mixed-metal organic compound (CH3NH3)2AgInBr6. This phase, which is not obtained by direct combination of reactants, is crystallized through the use of Pb2+ (from CH3NH3PbBr3) to modulat

We present a magnetic phase diagram of rare-earth pyrochlore ${\mathrm{Yb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$ in a $⟨111⟩$ magnetic field. Using heat capacity, magnetization, and neutron scattering data, we show an unusual field dependence of

A series of ${\mathrm{Yb}}_{2+x}{\mathrm{Ti}}_{2\ensuremath{-}x}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ doped samples demonstrates the effects of off-stoichiometry on ${\mathrm{Yb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$'s structure, proper

A novel technique is introduced for studying how rare earth ions are incorporated into the matrix of porous materials. Tb 3 + -doped silica sol-gel is annealed to form porous glass and immersed in an aqueous Gd(NO 3 ) 3 solution. Re-heating removes t

Analysis of glasses containing Eu and Tb dopants yields new insights about the role of Al 3+ co-doping in improving fluorescence yield of glasses containing rare earth (RE) dopants. Our work suggests that Al co-doping enhances fluorescence by two imp

High-temperature superconductivity has a range of applications from sensors to energy distribution. Recent reports of this phenomenon in compounds containing electronically active BiS2 layers have the potential to open a new chapter in the field of s
