X-ray diffraction (XRD) results indicate that the NiFe thin films had a face-centered cubic (FCC) structure. Post-annealing treatment increased the crystallinity of NiFe films over those at room temperature (RT), suggesting that NiFe crystallization yields FCC (111) texturing. Post-annealing treatments increase crystallinity over that obtained at RT. This paper focuses on the maximum alternative-current magnetic susceptibility(χac)value of NiFe thin films with resonance frequency(fres)at low frequencies from 10 Hz to 25000 Hz. These results demonstrate that theχacof NiFe thin films increased with post-annealing treatment and increasing thickness. The NiFe (111) texture suggests that the relationship between magneto-crystalline anisotropy and the maximumχacvalue with optimal resonance frequency(fres)increased spin sensitivity at optimalfres. The results obtained under the three conditions revealed that the maximumχacvalue and optimalfresof a 1000 Å-thick NiFe thin film are 3.45 Hz and 500 Hz, respectively, following postannealing atTA=250°C for 1 h. This suggests that a 1000 Å NiFe thin film post-annealed atTA=250°C is suitable for gauge sensor and transformer applications at low frequencies.

The magnetic susceptibility of the optimally doped Pr1-xLaCexCuO4in the superconducting state is calculated using thet-Jmodel of Cu-O planes, the Mori projection operator technique, and the dispersion of electron bands derived from photoemission experiments. The electron band folding across the antiferromagnetic Brillouin zone border, which is inherent in the crystal, leads to a commensurate low-frequency response. The same band folding causes the appearance of a supplementary spin-excitation branch, which coexists with usual spin excitations. This coexistence can explain two maxima observed in the frequency dependence of the susceptibility. The two nested spin-excitation branches lead to a comb of closely spaced peaks in momentum cuts, which presumably are not resolved in experiment, being seen as a broad commensurate peak up to 100 meV. Reasons for differences in magnetic responses of electron- and hole-doped cuprates are discussed.
