The present paper deals with the evidence of an unprecedented ordering in the Bi-rich part of the Bi Ca Mn O diagram, where the spin glass state is observed at low temperature. The χ −1 ( T ) curves of three compounds, corresponding to different C

The superstructure of Bi 1-x Ca x MnO 3 (x = 0.4 or 0.45), which exhibits a charge/orbital-ordered state at room temperature (Tco ≈ 330 K), has been successfully determined at different temperatures using single-crystal X-ray diffraction data and t

Phase equilibria in the MeCu(O) systems were studied using experimental and calculation procedures. XRD and DTA were used for experimental determination of thermodynamic data. For the calculation of the phase diagrams a mathematical solution of

The solid - liquid equilibria in the system were investigated using a soaking procedure accompanied by subsequent chemical and x-ray analysis. The obtained results completed by literature data were employed in the construction of the phase diagrams f

The TSFZ method has been used to grow crystals of the Bi-oxide superconductor of the Bi-n = 1 structure. The investigated compositions are Bi2Sr2CuO6+z, Bi2.3Sr1.7CuO6+z, and Bi2+xSr1.6- LayCuO6+z (x+y = 0.4). Except for the stoichiometric compositio

We report here resonant x‐ray scattering (RXS) experiments carried out at the Mn K edge in Bi1−xSrxMnO3 (x=0.3, 0.5) single‐crystals at room temperature. These compounds show a so‐called charge ordered (CO) state at room temperature. Strong r

Measurements of the electrical and thermal conductivities, thermopower and paramagnetic susceptibility have been performed on single crystal samples of Bi1/2Sr1/2MnO3 and complemented with the X-ray powder diffraction data. A pronounced hysteretic be

Enhanced growth of the (Pb,Bi) 2 Sr 2 Ca 2 Cu 3 O 10+z phase grains has been obtained by adding flux components as Sb 2 O 3 and NaCl respectively. The effects of such additives have been compared using XRD, SEM, EMA and transport measurements. In the
