“…Soft magnetic materials such as NiFe or CoFeB were conventionally used in spin valves due to the low Hc (μ0Hc ∼ 0.4 mT) and small Hsw (μ0Hsw ∼ 1.5 mT) in continuous films [7]. Conetic alloy (Ni77Fe14Cu5Mo4) is an FM material with smaller Hc than traditional soft magnetic materials such as CoFeB and NiFe [8], [9], [10]. By using Conetic alloy as free layer in micrometer-sized MR sensors, sensitivity of 3%/mT and μ0Hc smaller than 0.1 mT was achieved in the low field regime [11], [12], which enabled the detection of weak magnetism such as iron-oxide nanoparticles [13].…”

Magnetoresistive phenomena are widely used in the construction of magnetic field sensors for biological, space, automotive, etc., applications. For this purpose, a number of methods of obtaining and testing this type of sensor are used. Therefore, the motivation to take up this topic is to obtain a structure showing magnetoresistance and carry out electrical measurements in a magnetic field to confirm the assumptions about the presence of magnetoresistance. This paper focuses on the technology and measurements of thin-film three-layer resistors. Structures NiFeCuMo/Ti/NiFeCuMo with 100/10/100 nm thicknesses were developed in situ using a DC magnetron sputtering method. A scanning electron microscopy or energy dispersive spectroscopy analysis was conducted on a sample structure and the target alloy to establish their chemical composition. The occurrence of the giant magnetoresistance exhibited by the developed three-layers was successfully confirmed in the presence of an applied magnetic field and the maximum value of resistance changes ΔR was approximately 2.75 Ω. Additionally, the thickness of the resistors was determined with a confocal microscope to verify the accuracy of the applied deposition method.
