A magnetoresistance effect device and a magnetic head according to the present invention exhibit preferable magnetic characteristics and an excellent corrosion resistance. The magnetoresistance effect device includes an antiferromagnetic body formed in a fcc (face-centered cubic) structure and in an irregular phase and having a composition of A.sub.X --Mn.sub.1-X wherein A is at least one of Rh and Ru, and X is in a range from 0.05 to 0.25; and a ferromagnetic body whose magnetization state is controlled by the antiferromagnetic body. Moreover, the magnetic head includes an antiferromagnetic body formed in a fcc (face-centered cubic) structure and in an irregular phase and having a composition of A.sub.X Mn.sub.1-X wherein A is at least one of Rh and Ru, and X is in a range from 0.05 to 0.25; and a ferromagnetic body whose magnetization state is controlled by the antiferromagnetic body.
