description |
We investigate the anisotropic
magnetoelectric(ME) characteristics for the five-layer
magnetization-graded multiferroic composites(MGMC). The magnetic anisotropy and
corresponding anisotropic
magnetomechanical
effect,
demagnetization
effect and magneto-mechanical damping’s dependence on magnetic field direction
result in an obvious anisotropic ME coupling effect. The experimental results show that ME
voltage coefficient in H33 mode is remarkably larger than the
other ones (H11, H31 and
H13) over the whole Hdc range.
Correspondingly, ∂VME/∂Hdc arrives about 420mV/Oe
at an optimum bias magnetic
field of 46Oe, which is approximately 40 times larger than that of the
previous reported composite. Furthermore, it also demonstrates an obvious angular
dependence on dc magnetic
field. Taking advantage of these specifications, the MGMC can be used to
detect weak dc magnetic
field and its spatial orientation. |
