The cuprate superconductor, La[sub 1.68]Nd[sub 0.14]Na[sub 0.10]K[sub 0.082]CuO[sub 4], was prepared by selective precipitation from a NaOH/KOH eutectic melt at 350 [degree]C. Synchrotron x-ray-diffraction data indicate that the structure is related

The photoluminescence and X-ray luminescence of samples of LuTaO4-A (A=Ti, Pr, Sm, Eu, Gd, Tb, Dy, Tm) are reported. The results can be interpreted using simple models. Many samples show pronounced thermoluminescence after X-ray irradiation at room t

X-ray imaging via photostimulated luminescence (PSL) in barium fluorohalides is becoming important for various applications, in particular medical imaging. We describe the requirements for a PSL phosphor and then review the current understanding of t

Correlations of the coefficient of the "linear" term in the specific heat, $\ensuremath{\gamma}(0)$, and the discontinuity at ${T}_{c}$, $\ensuremath{\Delta}C({T}_{c})$, with a measured concentration of ${\mathrm{Cu}}^{2+}$ magnetic moments suggest t

X-ray and neutron diffraction studies of Sr2IrO4 and Sr2RhO4 reveal structural distortions from the ideal K2NiF4 structure, in which the IrO6 and RhO6 octahedra are rotated about the crystallographic c-axes by 11° or 9.7°, respectively. These rotat
