Magnetic susceptibility, optical, and adhesive properties of Co₄₀Fe₄₀V₁₀B₁₀ films

Abstract

The low-frequency alternating current magnetic susceptibility (χ ac ) property decreased when the frequency increased. The highest χ ac meant the spin sensitivity was maximized at an f res . Of all CoFeVB thicknesses, the 20-mm thickness had the highest χ ac value (9.85 × 10 −3 ) at an f res of 1000 Hz. The transmittance percentage decreased from 43% to 10% as the thicknesses changed from 10 to 40 nm. The absorbance of the CoFeVB films decreased. Finally, the surface energy revealed the lowest value at 20 nm. A high surface energy indicates high adhesive characteristics. The maximal surface energy of the 40-nm thickness was 38 mJ mm −2 , indicating excellent adhesion. The optimal magnetic performance of 20-nm film, because it exhibits the highest χ ac value.

Effect of Annealing on the Structural, Magnetic and Surface Energy of CoFeBY Films on Si (100) Substrate

“…The different thickness (t f ) of as-deposited and annealed CoFeBY films were also studied and we investigated the effects of crystallinity on the magnetic properties, adhesion and optical performance of the films. In our previous study, the properties of as-deposited Glass/CoFeBY and Si (100)/CoFeBY films were studied, as shown in Table 1 [ 23 , 24 ]. Continuing forward, we studied the as-deposited and annealed CoFeBY thin films.…”

Effect of Annealing on the Structural, Magnetic, Surface Energy and Optical Properties of Co32Fe30W38 Films Deposited by Direct-Current Magnetron Sputtering

“…This study also focused on the CoFeW thicknesses of various as-deposited and annealed treatments to investigate the influence of crystallinity with its magnetic properties, surface energy, and optical performance. In our previous research, the CoFeV and CoFeBV alloys were investigated for their specific properties, which is arranged in Table 1 [22][23][24][25][26]. Table 1 suggests that CoFeV and CoFeBV thin films were investigated at the as-deposited condition.…”
