High quality single crystals of BaFe 2 As 2 doped with aliovalent ions either out-of or in the basal plane of FeAs, namely hole-doped Ba 1รx K x Fe 2 As 2 and BaFe 2รx Mn x As 2 , or electron-doped BaFe 2รx M x As 2 (M = Co and Ni), were grown using self-flux method. By inducing a ''seed" in melt du
Thermal conductivity tensor has been measured using single crystalline Co-doped BaFe 2 As 2 down to 0.1 K and under magnetic fields up to 7 T. We observe peak anomalies both in the thermal conductivity and the thermal Hall conductivity in the superconducting state as an indication of enhancement of
