Özet

The BaxFe2-ySe2 (x=0.8) single crystal has been synthesized by using the one step technique at relatively lower temperatures. We have investigated structural properties of samples by using the XRD, SEM-EDX and magnetic properties. The SEM results clearly demonstrate that Ba ions are intercalated in the FeSe lattice. XRD result shows that the sample prepared has multi-phase structure. According to our M-H measurements perfect diamagnetism has been observed only in low field at 5 K. In addition, those curves indicate that the high field value and some impurities reveal ferromagnetic interactions. The superconducting transition was observed at around T-c approximate to 10.9 K.
