The laminar structures consist of alternating layers of the materials with high piezoelectric coefficients and of magnetostrictive or piezomagnetic materials. The thickness of the layers is usually about 0.5-1 mm and their square section is about 50-100 mm. The system of layers PZT/Terfenol-D has ME effect which is more than an order of magnitude larger than that of conventional composite [20]. Even... 

Coefficients aij T) depend explicitly on temperature T. Coefficients afj, aijki, are supposed to be temperature independent, constants giju and Vijkimn determine the magnitude of the gradient energy. Tensors gijki, Oijki and positively defined. Tensor is the surface excess elastic moduli, p, p is the surface stress tensor [81,82], is the surface piezoelectric or piezomagnetic tensor [67], qijki are the bulk striction coefficients Ciju are components of elastic stiffness tensor [83]. 

Here and are, respectively, coupling tensors of piezoelectric and piezomagnetic effects q j and q are the bulk electro- and magnetostriction coefficients. The flexomagnetic and flexoelectric coupling energy is...
