We have successfully synthesized a new family of Mg-intercalated superconductor MgxMNCl(M=Zr,Hf) with x≤1.0 using the electrochemical technique. The values of Tc ∼15 K for M=Zr and ∼25 K for M=Hf are almost independent of x even for heavily Mg-intercalated samples of Mg 0.8ZrNCl and Mg1.0HfNCl. Moreover, these values are the same as those of LixMNCl.
