Anisotropic thermodynamic and transport properties of single crystalline (Ba${}_{1-x}$K${}_x$)Fe${}_2$As${}_2$ (x = 0 and 0.45)

N. Ni, S. L. Bud'ko, A. Kreyssig +7

Single crystals of BaFe${}_2$As${}_2$ and (Ba${}_{0.55}$K${}_{0.45}$)Fe${}_2$As${}_2$ have been grown out of excess Sn with 1% or less incorporation of solvent. The crystals are exceptionally…
