Investigation of the Magnetic Properties of the Ni77/Fe14.4/Cu4.5/Mo0.5/Cr2.2/Si0.2 Alloy

The positron annihilation and Μössbauer effect measurements in permalloy Νi77/Fe14.4/Cu4.5/Mo0.5/Cr2.2/Si0.2 for different cooling rates have been performed. The results have been discussed in view of the magnetic properties of the alloy. Based on the energy spectra of positron annihilation radiation and $\text{}^{57}$Fe Mössbauer spectra, the positron polarization coefficient and the hyperfine field distributions have been calculated, respectively. We demonstrate that the results of both, positron annihilation and Mössbauer effect measurements, are in very close relation to the initial permeability μ$\text{}_{0.4}$ (at H = 0.4 A/m) and resistivity measurements.
