The PECP plate consisted of 0.68 volume-fraction PZT bars embedded in Spurr epoxy matrix, while the MSCP plates comprised 0.51 volume-fraction Terfenol-D particles embedded and magnetically aligned in Spurr epoxy matrix. The dielectric, magnetic and magnetoelectric properties of the laminate were measured as a function of both frequency and magnetic bias field. A giant magnetoelectric voltage coefficient (αE) of 15.4 V/cm·Oe was observed at the resonance frequency of ∼59 kHz under a relatively low bias field of 0.75 kOe. This resonance αE was ∼30 times larger than its non-resonance values, showing promising application of the proposed laminate in magnetoelectric conversion devices. | Description: | Symposium S Science and Technology of Hybrid Materials - ICMAT 2005: 3rd International Conference on Materials for Advanced Technologies; IUMRS-ICAM 2005: International Union of Materials Research Societies-9th International Conference on Advanced M, Singapore, 3-8 July 2005 | URI: | http://hdl.handle.net/10397/23242 | ISSN: | 1012-0394 | EISSN: | 1662-9779 | DOI: | 10.4028/www.scientific.net/SSP.111.147 |
