Effects of chemical substitution of the divalent transition metals has been systematically investigated in Mg₁₋ₓMₓB₂ (x=0.03; M=Mn, Fe, Co, Ni and Zn). Substitution of magnetic ions, i.e., Mn²⁺, Fe²⁺, Co²⁺ and Ni²⁺, for the Mg²⁺ ion suppresses T c: dT c/dx is the largest (= - 159 K) in the Mn-doped sample. We have found Zn-substitution increases T c (ΔT c ≈ 0.2 K at x=0.03), perhaps due to the enhanced density of state near the Fermi level.
