“…The annealing temperature was 400 °C with an exposure time of 1 min. This temperature was chosen because it is above the Curie temperature (

= 358 °C [ 52 , 53 , 54 ]), which allows orienting the magnetization of the magnetic domains of the Ni layer along the length of the ME sample in an external magnetic field. The magnitude of the external magnetic field was 1000 Oe.…”

The article is devoted to the theoretical and experimental study of a magnetoelectric (ME) current sensor based on a gradient structure. It is known that the use of gradient structures in magnetostrictive-piezoelectric composites makes it possible to create a self-biased structure by replacing an external magnetic field with an internal one, which significantly reduces the weight, power consumption and dimensions of the device. Current sensors based on a gradient bidomain structure LiNbO3 (LN)/Ni/Metglas with the following layer thicknesses: lithium niobate—500 μm, nickel—10 μm, Metglas—29 μm, operate on a linear section of the working characteristic and do not require the bias magnetic field. The main characteristics of a contactless ME current sensor: its current range measures up to 10 A, it has a sensitivity of 0.9 V/A, its current consumption is not more than 2.5 mA, and its linearity is maintained to an accuracy of 99.8%. Some additional advantages of a bidomain lithium niobate-based current sensor are the increased sensitivity of the device due to the use of the bending mode in the electromechanical resonance region and the absence of a lead component in the device.

“…The experimental results for the polycrystalline nickel (Ni) films that are fabricated using the dc mag netron sputtering were predominantly obtained for the films with the (111) texture [2,3,8,10]. It is demon strated in [11] for the Ni/Si(111) films that a variation in the potential of the Si substrate allows the fabrica tion of the Ni films with (111) or (200) textures.…”

The dependences of the magnetic properties and morphology of polycrystalline nickel (Ni) films with the (200) texture that are fabricated using the dc magnetron sputtering on the SiO 2 /Si(100) substrates on sputtering rate annealing temperature T, and film thickness d are analyzed. It is demonstrated that an increase in the sputtering rate from 17 to 35 nm/min does not affect the saturation magnetization 4πM and ferromagnetic resonance line width ΔH but leads to a significant increase in the coercivity H c for the films whose thickness d is greater than critical thickness d cr (d > d cr ). It is also demonstrated that d cr depends on both sputtering rate and annealing temperature. The films with the thickness d > d cr exhibit the stripe domain structure whose period increases with increasing d and rate v. The annealing of the films with d ≥ 40 nm at T ≈ 200-400°C results in an increase in ΔH and H c by a factor of 2-4, an increase in 4πM by 25%, an increase in grain size ξ by a factor of 20-30, and the formation of the stripe domain structure in the films that do not exhibit such structure prior to annealing and substantial strengthening of the (200) texture.
