Abstract-The most important milestone in the field of magnetic sensors was when AMR sensors started to replace Hall sensors in many applications where the greater sensitivity of AMRs was an advantage. GMR and SDT sensors finally found applications. We also review the development of miniaturization of fluxgate sensors and refer briefly to SQUIDs, resonant sensors, GMIs, and magnetomechanical sensors.

“…For the measurement of the terrestrial magnetic fields, magnetoelectric (ME) effect -based sensors have recently attracted much attention [1][2][3][4][5][6]. In comparison with the traditional types of magnetic sensors, which are based on fluxgate, Hall effects, superconducting quantum interference and giant magnetoresistance spin valves, etc.…”

Experimental investigations of the magnetization, magnetostriction and magnetoelectric (ME) effects were performed on sandwich -type Metglas/PZT/Metglas laminate composites. The results have been analyzed by taking into account the demagnetization contribution. The study has pointed out that the magnetic flux concentration is strongly improved in piezomagnetic laminates with a narrower width leading to a significant enhancement of the ME effects. The piezomagnetic laminates with the optimal area dimension were integrated to form a 2-D geomagnetic device, which simultaneously can precisely detect the strength as well as inclination of the earth's magnetic field. In this case, a magnetic field resolution of better than 10 −4 Oe and an angle precision of ± 0.1 o were determined. This simple and low-cost geomagnetic-field device is promising for various applications.

“…Many researchers have worked on composite materials to improve ME voltage coefficient. Due to potential of convertibility of magnetic field into electric field and vice versa [3][4][5][6][7][8], ME composite have large technological applications like transducer and sensor [9][10][11][12][13][14].…”
