We report growth of high-quality Bi2Sr2CaCu2Oz single crystals with dimensions 2 × 1 × 0.03 mm3 with a melt and growth technique. The composition of this crystal is homogeneous and very close to the stoichiometric composition. Structure characterization of a single crystal was realized by measuring the (001) x-ray diffraction. The lattice parameters of a typical crystal are a = 5.414(2) Å, b = 5.413(2) Å, and c = 30.823(10) Å. The superconducting temperature Tc = 95 K with a sharp transition width (10–90% level) between 6 and 10 K was determined from resistivity and dc susceptibility. We have measured the magnetization of Bi2Sr2CaCu2Oz single crystal under magnetic field applied along the c-axis. The anomalous second peak effect appeared between 20 and 30 K. We discuss the qualities of these crystals.

The temperature dependence of the voltage induced by the spin current was studied in an epitaxial thin-film La0.7Sr0.3MnO3 / SrIrO3 heterostructure deposited on a single-crystal NdGaO3 substrate. The spin current was generated by microwave pumping under conditions of ferromagnetic resonance in the La0.7Sr0.3MnO3 ferromagnetic layer and was detected in the SrIrO3 layer due to inverse spin Hall effect. A significant increase of half-width of the spin current spectrum along with the rise of amplitude of the spin current upon cooling from room temperature (300 K) to 135 K were observed.
