  • Giant magnetoelectric effects in serial-parallel connected Metglas/PZT arrays with magnetostrictively homogeneous laminates

    • Authors: Trinh, Dinh Cuong; Nguyen, Viet Hung; Vu, Le Ha; Phung, Anh Tuan; Do, Thi Huong Giang (2020)

  • To ensure the magnetostrictive softness, the homogeneity, the decrease of the shear-lag effect and the space-saving construction of narrowed longitudinal-transverse L-T magnetoelectric (ME) composites, a novel parallel-connected-multi-bars (PCMB) geometry of PZT/Metglas is proposed and investigated by simulation and experiment. 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 magn...

  • Nanostructure and magnetostriction in novel discontinuous terfecohan/YFe Exchange-spring type multilayers

    • Authors: Do, Thi Huong Giang; Nguyen, Huu Duc; Pham, Thi Thuong (2004)

  • Sputtered Tb(Fen--Co,) !-), -/YxFel x multilayers (0 < X < 0.2) with a T)FeCo layer thickness tn.KpCo - 1 2 nm and YFeCo layer thickness iYi-vr» - 10 nm hive been studied bv means of the X-ray diffraction (XRD), high-resolution tnnsmission electron microscopy (HR-TEM), conversion electron Mossbauer Sfectrometrv (CEMS) and magnetostriction investigations. The results show tlat nanocrystals are naturally formed and coexist within an amorphous matrix 11 Y, layers. For this discontinuous exchange-spring multilayers, a parallel magnetostrictive susceptibility ỵ,j: as large as 29.4x10 “ T 1, which is almost half of that (79.6x10 T ') of the Metglas 2605SC, was achieved.
