Structure and Magnetic Properties of Highly Resistive Fe-Al-N Films.

The GMI effect in nanocrystalline FeCuNbSiB multilayered films with a SiO2outer layer

“…At the temperature of 540˚C, the ratio reaches its highest value of 32.7% and decreases as the annealing temperature goes above 570˚C. The Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 films annealed below the temperature of 300˚C are still in the amorphous state, which is characterized using x-ray diffraction patterns and Mössbauer spectroscopy [18]. The orientation of the magnetic moment is parallel to the film's plane.…”

“…The increase in the GMI ratio is due to the inner stress relaxation. At the annealing temperature of 400˚C, the α-FeSi grains begin to separate from the amorphous matrix [18][19][20]. The orientation of the magnetic moment is perpendicular to the film's plane.…”

“…However, the film can be easily incorporated in ICs in practical applications. A very sensitive MI can appear in sandwich multilayered structures of two soft magnetic layers, separated by a highly conductive layer [16,18]. In this paper, the GMI effect of nanocrystalline FeCuNbSiB multilayered films has been studied as a function of annealing temperature and driving frequency.…”

Study on Head Core Materials with High <i>B_s</i> by Plating Methods

“…However, the materials with high p has not been studied well as compared with high Bs materials. Sputtered (Co,Fe)-AI-(N,O) alloys consisted of granular structure are reported to be high p materials with the p values of 150~3500IlQ-cm [19,20]. Soft magnetic films with high Bs and high p are shown in Fig.2, however, the some materials are not included in this figure because the p value is not reported.…”
