“…3 On the other hand, ME composites consisting of magnetostrictive and piezoelectric phases achieve strong ME effect, 4 especially when Metglas and Terfenol-D are used as the magnetostrictive layers. 5 It is important to note that because the ME composite effect depends on the magnetostrictive material's geometry, different physical characteristics of the magnetostrictive layer will result in different ME output 6 due to elastic losses and resonance quality. 7 Many research studies have been conducted to improve ME performance at resonance.…”

Trilayer Ni/PZT/Ni cylindrical magnetoelectric (ME) composites were prepared by electrodeposition, a process, which creates sub-millimeter raised edges due to current concentration near sharp points. The ME response in both axial and vertical modes was measured with the edges, with only outer edges removed, and with both outer and inner edges removed. The ME voltage coefficient improved at resonance by 40% and 147% without the edges in the vertical and axial modes, respectively. The observed improvements in three different samples were only present at the ME resonance and no changes were detected outside of the ME resonance. Mechanical quality factor at resonance also improved with no effect on the resonant frequency. Experimentally demonstrated minor geometry changes resulted in substantial ME improvement at resonant frequency. This study demonstrates device performance optimization. The observed effects have been attributed to improved vibrations in terms of decreased damping coefficient and enhanced vibration amplitude at resonance.

“…[2][3][4][5][6] While the latter effect is useful for the electric field control of magnetic properties, 7,8 the direct ME effect allows building ultrasensitive magnetic field sensors. [9][10][11][12] It is worth noting that the spectrum of possible applications of multiferroic composites is obviously much wider, including memory, domain wall motion control, acoustically driven ferromagnetic resonance (FMR), etc. [13][14][15][16] Among different connectivity types of the FM and FE phases in ME composites, 2-4 the 2 2 type laminate structures demonstrate the maximum efficiency due to low leakage currents and a strong mechanical coupling between the FE and FM phases.…”

“…Among different commercially available single crystals, the lead magnesium niobate lead titanate (PMN-PT) 25 and lead zinc niobate lead niobate (PZN-PT) demonstrate the highest piezocoefficients and thus are frequently used in the design of different laminate ME structures. 11,12,[26][27][28][29][30] The main disadvantages of PMN-PT and PZN-PT are low Curie and depolarization temperatures ($100 C), chemical and electrical instabilities, non-linear behavior, uneasy growth of high-quality crystals, and a very high price. Due to these factors, other single crystalline ferroelectrics or just piezoelectrics are being tested at present.…”

Electromechanical and magnetoelectric properties of Metglas/LiNbO 3 /Metglas trilayers have been studied in the frequency range from 20 Hz to 0.4 MHz. A trilayer of Metglas/PMN-PT/Metglas prepared in the same way was used as a reference. Though PMN-PT has much larger charge piezocoefficients than LiNbO 3 (LNO), the direct magnetoelectric voltage coefficient is found to be comparable in both trilayers due to the much lower dielectric permittivity of LNO. The magnitude of the direct magnetoelectric effect in the LNO trilayers is about 0.4 V/cm Oe in the quasistatic regime and about 90 V/cm Oe at the electromechanical resonance. Calculations show that the magnetoelectric properties can be significantly improved (up to 500 V/cm Oe) via controlling the cut angle of LNO, choosing the appropriate thickness ratio of the ferroelectric/ferromagnetic layers and a better bonding between Metglas and LNO. Advantages of using LiNbO 3 -type ferroelectrics in magnetoelectric composites are discussed. V C 2013 AIP Publishing LLC. [http://dx

“…[1][2][3][4][5][6] For obtaining a more sensitive magnetic sensor, the magnetostrictive phase in the laminate composite is recommended to have higher effective relative permeability µ r and lower saturation magnetization µ 0 M s . 7,8 But unfortunately, most of the magnetostrictive materials have low µ r . 9,10 Recently, the ME composites with Metglas have highest sensitivity and lowest noise for ME sensors.…”

Improved magnetoelectric effect in magnetostrictive/piezoelectric composite with flux concentration effect for sensitive magnetic sensor

The magnetoelectric (ME) composite with the flux concentration effect is designed, fabricated, and characterized for detecting weak ac magnetic-field. The high-permeability Fe73.5Cu1Nb3Si13.5B9 (FeCuNbSiB) foils act as flux concentrators and are bonded at the free ends of traditional ME laminates. With the improved ME responses in the proposed ME composite based on the flux concentration effect, the output sensitivities under zero-biased magnetic field can reach 7 V/Oe and 15.8 mV/Oe under the resonance frequency of 177.36 kHz and the off-resonance frequency of 1 kHz, respectively. The results indicate that the proposed ME composites show promising applications for high-sensitivity self-biased magnetic field sensors and ME transducers.
