We report on crystal growth and about physico-chemical studies on SryBa1?yFClxBr1?x (y = 0, 0.5, and 1) compounds doped with Sm. Persistent spectral hole burning at 300 K is further reported on Sr0.5Ba0.5FCl0.5Br0.5:Sm single crystals.

The composition of high altitude ice clouds is still a matter of intense discussion. The constituents in question are ice and nitric acid hydrates but the exact phase composition of clouds and its formation mechanisms are still unknown. In this work

Europium-doped crystalline Ba7F12Cl2 phosphors have been prepared at temperatures between 650 and 900 °C using alkali chloride fluxes, yielding both disordered (with the incorporation of small amounts of Na) and ordered crystal modifications. The wh

In analogy to the synthesis of polycrystalline M2NaIO6 (M = Ca, Sr, Ba) by precipitation in water at 90 °C, the title compound was first prepared as a metastable compound. The stable modification of Pb2NaIO6 was obtained by a heat treatment to 400

The compound Ba5I2O12 was synthesized by heating a precipitate of dissolved Ba(OH)2·8H2O and H5IO6. Rb2O was added to increase the crystallite size. The crystal structure was determined from conventional laboratory X-ray diffraction data by using a

Hysteresis loops and magnetostriction were measured on ring-shaped ${\rm Fe}_{85}{\rm Ga}_{15}$ samples. The samples were annealed at $T=980^{\circ}{\rm C}$ for 100 h and cooled from annealing temperature in two different ways: one was slowly cooled

The crystal structures of Na2Mg3(OH)2(SO4)3·4H2O and K2Mg3(OH)2(SO4)3·2H2O, were determined from conventional laboratory X-ray powder diffraction data. Synthesis and crystal growth were made by mixing alkali metal sulfate, magnesium sulfate hydrate
