Özet

Superconductivity and magnetic properties were studied for La and Pt substituted (Ca, Ba) 0.9 La 0.1 Fe 1.9 Pt 0.1 As 2 samples using structural, resistivity and magnetic measurement techniques. All bulk samples were synthesized by solid-state reaction method and annealed under a specific annealing technique with a time-dependent annealing process in vacuumed quartz tubes. ThCr 2 Si 2 -type crystal structure was concluded for both samples varying with in- and out-of-plane lattice parameters. The superconducting critical temperatures were determined by resistivity and under H = 20 Oe magnetization measurements, which were performed between the temperature ranges of 0-200 K. The upper and lower critical fields were determined and possible Meissner effects were roughly figured out to understand the level of shielding from M-H measurements. The maximum critical temperature was obtained from Ca 0.9 La 0.1 Fe 1.9 Pt 0.1 As 2 .
