Thermal stability of the in-plane magnetic anisotropy and the coercivity of nanocrystalline CoFeNi films

On the composition depth profile of electrodeposited Fe–Co–Ni alloys

“…Low coercivity and high saturation induction were of prime importance [1][2][3][4][5][6][7][8][9], while other magnetic properties such as anisotropy [9][10][11][12], high-frequency permeability [13] and magnetoimpedance properties [14,15] were also examined. Structural properties of ED Fe-Co-Ni alloys were studied in detail [6,7,16,17].…”

Variation of structure and magnetic properties with thickness of thin Co59Fe26Ni15 films

“…The samples were magnetically soft with coercivity in the range H c ¼ 1210 Oe and uniaxial magnetic anisotropy up to H k ¼ 20 Oe [6]. The dependence of magnetic properties on the film thickness can be one of the reasons of variation of the H c and H k values from one sample to another.…”

“…The CoFeNi layers were produced by electrodeposition at room temperature in the galvanostatic mode on copper underlayer (300 nm), which was sputtered on Crcovered (20 nm) oxidized (200 nm) silicon [6] 0.1 T, parallel to the plane, was applied in order to introduce in-plane uniaxial anisotropy. Different electrodeposition bath composition, current densities and temperature have been tested.…”

“…[5]. The magnetic coercivity, H c , and anisotropy, H k , were evaluated from hysteresis loops measured by VSM at room temperature with the magnetic field applied in the easy and hard directions, respectively, and varied in the range of 71 kOe [6].…”

Ultra-soft magnetic films: micromagnetism and high frequency properties

“…Glass or silicon substrates with or without polymer or Cu underlayers were used. The Co 59 Fe 26 Ni 15 films were produced by electrodeposition at room temperature in the galvanostatic mode on copper underlayer (300 nm) which was sputtered on Cr-covered (20 nm) oxidized (200 nm) silicon [8]. In both cases, a horizontal magnetic field parallel to the plane was applied in order to introduce in-plane uniaxial anisotropy.…”
