Abstract: Modern electronic devices development steady trends toward miniaturization and multifunctionality. The application of such advanced devices is often realised by superimposing two different effects. In recent years, there was great interest shown in multiferroic materials in form laminated heterostructures taking advantage of mentioned superposition. In these stacked structured electric and magnetic properties are strain coupled leading to the possibility of controlling either magnetic polarization by application of electric fields or electric polarization by means of applied magnetic fields. In this paper novel construction of piezoelectric transformer was proposed with electric current induced magnetic field generation, without any coil or wires. This magnetoelectric laminate Piezoelectric Transformer from one layers of investigated piezoelectric material and second layer of commercial magnetostrictor was fabricated. This construction exhibits many interesting and unusual piezomagnetic properties and a demonstration of output voltage gain controlling via the application of magnetic field across the new heterostructure is presented.
