“…It should be mentioned that a magnetic field must be applied during the deposition in order to give them the proper sensing capability. In addition, some studies have also been reported on the electrodeposition of GMR multilayers [ 12 ]. The patterning of the structures is usually carried out by UV lithography (with possibility of direct-writing and lift-off approaches), but electron beam lithography can also be used for obtaining sub-micron structures (2000 × 100 nm

, as reported in [ 13 ]).…”

Less than thirty years after the giant magnetoresistance (GMR) effect was described, GMR sensors are the preferred choice in many applications demanding the measurement of low magnetic fields in small volumes. This rapid deployment from theoretical basis to market and state-of-the-art applications can be explained by the combination of excellent inherent properties with the feasibility of fabrication, allowing the real integration with many other standard technologies. In this paper, we present a review focusing on how this capability of integration has allowed the improvement of the inherent capabilities and, therefore, the range of application of GMR sensors. After briefly describing the phenomenological basis, we deal on the benefits of low temperature deposition techniques regarding the integration of GMR sensors with flexible (plastic) substrates and pre-processed CMOS chips. In this way, the limit of detection can be improved by means of bettering the sensitivity or reducing the noise. We also report on novel fields of application of GMR sensors by the recapitulation of a number of cases of success of their integration with different heterogeneous complementary elements. We finally describe three fully functional systems, two of them in the bio-technology world, as the proof of how the integrability has been instrumental in the meteoric development of GMR sensors and their applications.

“…According to literature the GMR effects depends on the overall thickness of multilayer system. Giant magnetoresistance of multilayers enhances strongly with increase the number of bilayers [12]. Also magnetic and non-magnetic layer thickness have an influence on GMR.…”

“…Some references report that in the case of electrochemically deposited multilayer Cu/Ni systems GMR effect was barely 1-1.5% [7,9]. Tokarz et al [13] presented that the GMR value of Cu/Ni multilayer system is 2.5% with current flowing in plane of the multilayer and the applied magnetic field was 0 to 1.5 T at 50 K. The maximum of 7% GMR was achieved when the total number of bilayer was 6000 [12]. Regardless of magnetic field, the resistance of multilayer systems is kept constant (Fig.…”

The increasing demand for thin-layer materials influences on development of their production technologies and a range of potential applications. The properties of these materials (e.g. physical properties) can find new applications and solve existing limitations. Multi-and thin-layer metal systems are a special group of materials which can be successfully used for suppression of electromagnetic waves. Properly designed multilayer systems can exhibit the effect of a giant magnetoresistance. The research results include morphology observations and study of surface topography of Cu/Ni multilayer systems with nanometric layers. The layers were electrolytically produced on a thin copper foil substrate. The investigations of the physical properties of the systems have shown that quantity and thickness of the layers in the multilayer system have an effect on magnetic properties. The obtained layers are characterized by good quality. Moreover, they are compact and homogeneous. The topographical studies have not detected major surface defects of multilayer systems.

Soft ferromagnetic permalloy (NiFe) thin films are promising for applications in spintronic devices because of their constituent electrical and magnetic properties. Electron beam evaporation and sputtering techniques have been used to deposit NiFe thin films. For in situ stacking of NiFe with functional complex oxides, the pulsed laser deposition (PLD) method is highly desirable. However, the growth of high‐quality NiFe (and non‐oxide thin films in general) by PLD remains a formidable task. Here, high‐quality NiFe thin films of various thicknesses on oxide/non‐oxide substrates with desirable magnetic properties by PLD at room temperature are reported. The magnetic properties are found to be strongly dependent on the laser fluence of the deposition process. The laser fluence of 4 J cm−2 produces the highest magnetization of ≈547 emu cc−1. The small coercivity (few Oersted) and sharp ferromagnetic switching behavior indicate uniaxial anisotropy with an easy axis along the in‐plane direction. In addition, thickness‐dependent magnetodynamics characterizations are studied via ferromagnetic resonance. These results offer significant insight into the PLD‐based development of thin metal magnetic films.
