| 英文摘要 | We experimentally and theoretically report the magnetoelectric effect in a composite made by sandwiching one shear mode 0.7pbmg(1/3)nb(2/3)o(3)-0.3pbtio(3) (pmn- pt) piezoelectric single crystal plate between two longitudinally magnetized ndfeb permanent magnet bars along the length direction of the pmn- pt plate. the magnetoelectric effect originates from the mechanically mediated product effect of the torsional magnetic force effect in the ndfeb bars and the shear piezoelectric effect in the pmn- pt plate. the composite exhibits a magnetoelectric voltage coefficient of similar to 32.7 mv/ cm oe with a flat frequency response in the measured range of 0.1 - 30 khz. the induced magnetoelectric voltage shows a good linear relationship to the applied ac magnetic field with amplitude varying from 10(-7) to 10(-3) t. other distinct features include no need to have a magnetostrictive phase, low joule heating loss, and high scale- down capability. these suggest promising applications of the torsional- shear mode composite in power- free magnetic field sensors.
