Magnetoelectric (ME) composites consisting of piezoelectric materials and magnetostrictive materials have been studied extensively due to their large ME effects than those in single phases [1-2], offering promise for magnetic moment sensing and other applications. In these composites, the ME coefcient is dependent upon the elastic coupling that occurs at the interface between piezoelectric and magnetostrictive...
Magnetoelectric (ME) response has attracted continuously increasing interest in the past decades due to its potential applications in many new multifunctional devices, including magnetic storage, magnetic sensors, current sensors, and energy harvesters.[1] In general, single-phase ME materials are difficult to be utilized in such devices because the ME responses are weak and mostly appear at low temperature...
Over the last decade, multiferroic laminate heterostructures, consisting of the piezoelectric layer (such as PZT) and the magnetostrictive layer (such as Terfenol-D), have attracted considerable attention due to their high Curie or Neel temperature and large magnetoelectric (ME) effect at room temperature. The ME laminate materials have demonstrated potential in many applications such as transducers,...
Acoustic switches (ASs) can control the wave propagation in media for acoustic wave applications including smart acoustic structures and materials [1]. Especially, contactless magnetic-controlled AS based on magnetoelastic Terfenol-D/epoxy phononic crystals has been developed by exploiting external static magnetic fields [2]. However, the magnetic-controlled AS exhibits an ultra-high threshold of...
There is growing interest in energy scavenging from natural vibration sources to power autonomous wireless telemetry devices. Vibration energy is typically converted into electrical energy using piezoelectric, electromagnetic, or electrostatic transduction mechanisms [1]. Despite the transduction mechanisms and novel structures, there is still an obstacle facing realistic implementation in most of...
Since the piezoelectric/magnetostrictive laminate composite exhibits a strong magnetoelectric (ME) effect, it provides a novel method for detecting ac magnetic field. There are a number of researches on the development of ME composites and their applications in detecting magnetic fields. Dong et al. demonstrates the possibility of fabricating ac magnetic field sensors with high performances[1]. Especially,...
In recent years, electric field-modulated ferromagnetism, called converse magnetoelectric (CME) effect, has attracted great interest due to their many potential device applications such as coil-less magnetoelectric flux switching [1], high-density data storages [2] and tunable inductors [3]. It has been reported that the maximum CME effects in most multiferroics composites are usually achieved under...
