We synthesized the samples Sr(1-x)Sm(x)FFeAs with a ZrCuSiAs-type structure. These were characterized by resistivity and susceptibility. It is found that substitution of rare earth metal for alkaline in this system suppresses anomaly induces superconductivity. Superconductivity at 56 K nominal composition Sr(0.5)Sm(0.5)FFeAs realized, indicating superconducting transition temperatures iron arsenide fluorides can reach as high oxypnictides same
We have successfully synthesized a new layered pnictide-oxide: BaTi(2)As(2)O. It shares similar characteristics with Na(2)Ti(2)Sb(2)O. The crystal has structure tetragonal P4/nmm group (a = 4.047(3) Å, c 7.275(4) Å). resistivity shows an anomaly at 200 K, which should be ascribed to SDW or structural transition. transition is confirmed by magnetic susceptibility and heat capacity measurements. These behaviors are very those observed in parent compounds of high-T(c) iron-based pnictide...
This study investigates Beam Line Absorbers (BLAs) for the Hefei Advanced Light Facility (HALF). A ferrite-based BLA prototype was developed, demonstrating high-power handling capacity up to 10[Formula: see text]kW, ultra-high vacuum performance better than [Formula: text] text]mbar, and high absorption efficiency in critical frequency ranges. Subsequently, more compact designs with reduced longitudinal length were explored, investigating ferrite-only, silicon carbide (SiC)-only, hybrid...
