Description
In recent years Fe-based superconductors have spurred much research due in part to the large number of compounds that have been discovered to exhibit superconductivity and the interesting interplay between magnetism, structure, and the superconducting ground state. In addition, the high Bc2s exhibited by these materials make these compounds interesting for low-temperature, high-field applications. However, recent work has also shown that Tcs of up to 100 K can be achieved in single-layer thin films of this interesting compound. In this poster we detail the AFRL’s attempts at large single crystal synthesis of bulk FeSe. Doping of FeSe single crystals will be attempted so that the fundamental electrical, magnetic, and thermodynamic properties can be discerned, including effects on the superconducting phase diagram (Tc, Bc2, Jc). These data will be intercompared so as to deconvolution of the effects of increasing the interlayer layer spacing via intercalation from the effects of doping.
