Single crystals of superconducting SmFeAsO1−xFy grown at high pressure

Single crystals of SmFeAsO1−xFy of a size up to 120 × 100 μm2 have been grown from NaCl/KCl flux at a pressure of 30 kbar and temperature of 1350–1450 ◦C using the cubic anvil high-pressure technique. The superconducting transition temperature of the obtained single crystals varies between 45 and 53 K. Obtained crystals are characterized by a full diamagnetic response in low magnetic fields and...

Effect 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...

First-principles study of pentaerythritol tetranitrate single crystals under high pressure: vibrational properties

First-principles theoretical methods were used to investigate the vibrational properties of pentaerythritol tetranitrate (PETN) under hydrostatic compression up to 4 GPa. Bond lengths and bond angles for the PETN molecules and the pressurevolume relation for the crystal under high pressure were calculated and compared with previous calculations and with experimental results. Based on the calcul...
