In this case, Metglas layers are structured in different geometries from the conventional single bar (c-SB) to conventional separated multiple bars (c-SMB), elongated separate multi-bar (e-SMB) and n-magnetic-bar based PCMB (n-PCMB). This n-PCMB geometry divides the conventional ME configuration into n parallel-connected ME units (n-PCMEU) according to the magnetic geometries. The optimal ME performance with the largest ME voltage coefficient aE of 630 V/cm.Oe is achieved in PCMEU with two Metglas bars (n = 2). The ME voltage coefficient can be further enhanced by integrating m of these optimal PCMEUs in series to form a serial-parallel ME unit array m-S (n-PMEU)A. The aE value increases by a factor of 3.6 and reaches 2.238 kV/cm.Oe for 4-S (2-PMEU)A, a factor that is almost equal to m. The resulting 4-S (2-PMEU)A sensor possesses an extremely high sensitivity of 18.1 mV/nT, with a resolution of 10�1 nT. date: 2020-07-03 date_type: published publisher: Elsevier B.V contact_email: giangdth@vnu.edu.vn full_text_status: public publication: Journal of Science: Advanced Materials and Devices volume: 5 pagerange: 354-360 refereed: TRUE issn: 2468-2179 funders: National Research Program projects: DTDL.CN-02/17 citation: Trinh, Dinh Cuong and Nguyen, Viet Hung and Vu, Le Ha and Phung, Anh Tuan and Do, Dinh Duong and Ho, Anh Tam and Nguyen, Huu Duc and Do, Thi Huong Giang (2020) Giant magnetoelectric effects in serial-parallel connected Metglas/PZT arrays with magnetostrictively homogeneous laminates.
