The recently discovered FeAs-based superconductors are a new, promising set of materials for technological and basic research. They offer transition temperatures as high as 55 K as well as essentially isotropic, and extremely large, upper, superconducting critical fields, in excess of 40 T at 20 K. In addition, they may well provide insight into exotic superconductivity that extends beyond just FeAs-based superconductivity, perhaps even shedding light on the still-perplexing CuO-based high-Tc materials. Whereas superconductivity can be induced in the RFeAsO (R = rare earth) and AEFe2As2 (AE = Ba, Sr, Ca) families by several means, transition metal (TM) doping of BaFe2As2 [e.g., Ba(Fe1–xTMx)2As2] offers the easiest experimental access to a wide set of materials and states. In this review, we present an overview and summary of the effect of TM-doping (TM = Co, Ni, Cu, Pd, and Rh) on BaFe2As2. The resulting phase diagrams reveal the nature of the interaction between the structural, magnetic, and superconduct...

• Superconductivity in iron compounds (2011, methodology): “A common feature of doping the MFe2As2 materials on the Fe site has been the separation for finite doping of TS from TSDW (see results similar to those for Co doping for TS=TSDW splitting upon doping with TM ¼ Ni and Rh in BaFe2 yTMyAs2 by Canfield and Bud’ko, 2010).”
