Magnetic, transport, and thermodynamic properties of CaMn2O4 single crystals
Physical properties including magnetic susceptibility, room-temperature electrical resistivity, thermal conductivity, heat capacity, and thermal expansion are reported for high quality single-crystal samples of marokite CaMn2O4. We determined that CaMn2O4 is highly electrically insulating and exhibits long-range antiferromagnetic order below TN=217.5 0.6 K with easy axis along a. Anisotropic th...
متن کاملPreparation and transport properties of non-hydrated Na0.5CoO2 single crystals
Single crystals of Na0.5CoO2 were obtained through a flux method followed by deintercalation of sodium. The Na0.5CoO2 samples were found to be vulnerable to water in the air and a hydration process in which H2O molecules fill oxygen vacancies in CoO2 layers is suggested to be responsible for the unusual vulnerability to water. The transport properties, including resistivity (ρ), thermopower (S ...
متن کاملGROWTH OF ZnS SINGLE CRYSTALS BY CVT TECHNIQUE UNDER DIFFERENT MASS TRANSPORT STABILITY CONDITIONS
Abstract: A thermodynamic model was used to find out the optimum temperature for the growth of ZnS single crystals in closed ampoules by chemical vapor transport technique. Based on this model 1002 °C was found to be optimum temperature for 2 mg/cm3 concentration of transporting agent (iodine). ZnS Crystals were grown in optimum (1002 °C) and non-optimum (902 °C and 1102 °C) temperatures. The c...
متن کاملEffect of impurities on the optical properties of KTP single crystals grown from flux
In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...
متن کاملOPTICAL PROPERTIES OF CdIn2S4 SINGLE CRYSTALS
-The optical absorption of CdIn2S4 single crystals has been measured at several temperatures in the spectral range from 0.4 to 0.8 p. The interband gap for the indirect allowed transition was found to have a temperature coefficient of 9.5 X 10J eV/deg between 100 K and 300 K and to have a value of 2.7 eV when extrapolated to 0 K. From a temperature dependence of the photocurrent corresponding t...
