We have studied the influence of alloying with a fourth element on the temperature of ferromagnetic ordering TC in Ni-Mn-Ga Heusler alloys. It is found that TC increases or decreases, depending on the substitution. The increase of TC is observed when Ni is substituted by either Fe or Co. On the contrary, the substitution of Mn for V or Ga for In strongly reduces TC.
