Crystal growth and phase diagram of 112-type iron pnictide superconductor Ca1−yLayFe1−xNixAs2
  We report a systematic crystal growth and characterization of Ca1−yLayFe1−xNixAs2, the newly discovered 112-type iron-based superconductor. After substituting Fe by a small amount of Ni, bulk superconductivity is successfully obtained in high-quality single crystals sized up to 6 mm. Resistivity measurements indicate common features for transport properties in this 112-type iron pnictide, suggest strong scattering from chemical dopants. Together with the superconducting transition temperature Tc, and the Néel temperature TN determined by the elastic neutron scattering, we sketch a three-dimensional phase diagram in the combination of both Ni and La dopings.
