Single-crystals of Na1−δFeAs with partial substitution of Fe by Co, Rh, Ni, Ru, Pd, Cr and Mn were grown by a self-flux technique. A systematic investigation of the structure by powder X-ray diffraction, temperature dependence of magnetic susceptibility, electronic transport and specific heat were carried out. We map out the corresponding electronic phase diagram for the Co substituted Na1−δFeAs, compared with Literature [1, 2] and map out the corresponding electronic phase diagram for the Rh substituted Na1−δFeAs.
