Abstract

GMR was investigated in inhomogeneous Ni1-xMnx alloys (x = 0.20-0.3) of nano-scale, where ordered single-domain clusters are distributed in disordered Ni-rich or Mn-rich matrices. The GMR depends remarkably on x: GMR for 0.20≤x≤0.24 is small (Type I) and for 0.26≤x≤0.30 has a maximum of -3.6% at x = 0.27 (Type II). Types I and II are caused, respectively, by ferromagnetic and antiferromagnetic interactions between domains.
