| Description |
We report synthesis of S doped FeTe1-xSx (x= 0.00 and 0.10) single crystals using flux free method via solid state reaction. Single crystal XRD patterns of FeTe1-xSx (x= 0.00 and 0.10) confirm the single crystalline property, as the crystals are grown in (00l) plane only. Powder XRD result of FeTe1-xSx (x= 0.00 and 0.10) crystals show that crystalline in tetragonal structure having P4/nmm space group. Rietveld refinement results show that both a and c lattice parameters decreases with S doping of 10% at Te site in FeTe1-xSx. Detailed scanning electron microscopy (SEM) image of FeTe0.90S0.10 shows that the growth of crystal is in slab-like morphology. Electrical resistivity measurement results confirm the superconductivity in S doped 10% sample at Te site and superconducting transition T-c(onset) occurs at 9.5K and T-c(offset) (rho=0) occurs at 6.5K. rho-T measurement has been performed under various magnetic field up to 12 Tesla down to 2K. Upper critical field H-c2(0), for x= 0.10, which comes around 70Tesla, 60Tesla and 45Tesla of normal resistivity criterion rho(n)=90%, 50% and 10% criterion respectively.
