Single crystal growth and effects of Ni doping on the novel 12442-type iron-based superconductor RbCa2Fe4As4F2

Single crystal growth and effects of Ni doping on the novel 12442-type iron-based superconductor RbCa2Fe4As4F2

The recently discovered 12442-type iron-based superconductors (IBSs), ACa _2 Fe _4 As _4 F _2 (A = K, Rb, Cs), are intrinsically self-hole doped stoichiometric compounds that exhibit superconductivity with T _c = 30–33.5 K. In this paper, single crystals of Ni doped RbCa _2 (Fe _1− _x Ni _x ) _4 As...
