Abstract
Magnetoelectric composites have recently been attracting attention owing to their possible application in various advanced electronics. The piezoelectric material used in a magnetoelectric composite is an important determinant of the electrical performance of the device. In this study, we report on the fundamental characteristics and magnetoelectric application of a 15-mode piezoelectric composite. The centimeter-scale 15-mode piezoelectric composite implemented by a novel fabrication process exhibits successful 15-mode operation along with excellent piezoelectric properties d15â¯=â¯793â¯Ãâ¯10â12â¯Câ¯Nâ1, g15â¯=â¯32â¯Ãâ¯10â3â¯Vâ¯mâ¯Nâ1, k15â¯=â¯0.62, and d15·g15â¯=â¯25376â¯Ãâ¯10â15â¯m2â¯Nâ1. Magnetostrictive-piezoelectric laminate structures designed to generate shear stress were fabricated using the 15-mode piezoelectric composites, and their magnetoelectric characteristics were investigated systematically. A giant magnetoelectric voltage coefficient of 18.4â¯Vâ¯cmâ1â¯Oeâ1 was obtained at a low frequency of 660â¯Hz from the laminate, indicating the potential of the 15-mode piezoelectric composite for application in high-performance magnetoelectric devices.
