We investigated the magnetic properties of Ni<SUB>1−<I>x</I></SUB>Mn<I><SUB>x</SUB></I> (<I>x</I>=0.20–0.30) alloys with dispersed nanoparticles having a ferromagnetic Ni<SUB>3</SUB>Mn ordered phase, which is caused by suitable heat treatment. Magnetic analysis shows that for 0.3≥<I>x</I>>0.25 alloys interaction between 4–10 nm particles through Mn-rich matrix is antiferromagnetic. The Néel temperature increases with both Mn concentration and long-range-order parameter. On the contrary, for 0.25><I>x</I>≥0.20 alloys, interaction between ∼ 4 nm particles through Ni-rich matrix is ferromagnetic. These alloys exhibit soft magnetic properties and have permeability of 400–600 for 1–500 kHz high frequency.
