Three years ago the present investigators studied the relation between the magnetic permeability and the order-disorder transformation (Ni3Mn) in the ferromagnetic Ni-Mn alloys and found a new magnetic alloy “Nimalloy” having a high permeability.<BR>A further investigation on the influence of the addition of iron on the magnetic properties of Nimalloy has revealed that the initial and maximum permeabilities of the alloys are increased generally by the addition of iron: The alloys containing 19.37% manganese and 4.36% iron, and 19.33% manganese and 4.55% iron show an initial permeability of 39,200 and a maximum permeability of 213,000, respectively, when they are cooled at the rate of 26°C/sec from 600°C. And in the former alloy the magnetic hysteresis loss is 5.40 erg/cm3/cycle, the coercive force 0.0042 Oe for the maximum induction of 2000 G, and the specific electric resistance 68.5 μΩ-cm at 20°C.
