- The crystal structure and magnetic properties of polycrystalline alloys $Fe_{62.5}Ni_{37.5},$ $Fe_{60}Ni_{40},$ $Fe_{50}Ni_{50}$ obtained by arc-melting and $Fe_{40}Ni_{40}B_{20}$ alloy obtained by melt spinning technique were investigated by X-ray, magnetostatic and Mössbauer effect methods. The X-ray measurements show that $Fe_{40}Ni_{40}B_{20}$ alloy has a face-centered structure (fcc) which means that boron did not cause an amorphous rendering. The lattice constants for this alloy (a = 3.53 Å) is smaller than for FeNi alloys (a > 3.57 Å) which suggests that boron atoms were built-in in the crystal lattice. The Curie temperature of this alloy is more than 150 K higher in comparison with the of FeNi alloys, but the magnetic moment connected with this alloy is more than 0.17 $μ_{B}$/atom smaller than the magnetic moments of FeNi alloys. The shape of hyperfine field distribution for $Fe_{40}Ni_{40}B_{20}$ is similar to the shape of hyperfine field distribution for the investigated fcc $Fe_{62.5}Ni_{37.5}$ alloy, but both are different from another investigated hyperfine field distribution of FeNi alloys.
