In prior chapters, we have seen that two-phase magnetostrictive/
piezoelectric laminates or composites exhibit large ME coupling

dc,opti
for L–T and L–L ME
laminates are about 500 Oe, whereas those operated in T–T modes
may have H
dc,opti
as high as 4000 Oe [17, 24]. These relatively high H
dc,opti
are due to the low magnetic permeability μ
