Effect of titanium and titanium dioxide doping on the superconducting properties of the Fe1.02Se compound

In present study the effect of joint doping with titanium and titanium dioxide on the superconducting properties of iron selenide FeSe was carried out. It was found that doping of titanium and titanium dioxide with a concentration of y = 0.04 leads to a deterioration in superconducting properties, and a further increase in the concentration of dopants leads to a complete suppression of the transition to the superconducting state.
