Macroscopic characterization of magneto electric materials — •Ahmadshah Shahab Nazrabi — ahmadshah.nazrabi@uni-due.de

The class of multiferroic materials combine two ferroic ordering phenomenas, the ferromagnetic and ferroelectric. Magneto-electric materials have two main potential applications: Precise sensors for magnetic measurement technology in medicine and fatigue non-volatile memory for the electronics. In both cases the coupling between electric and magnetic variables must be still optimized. The coupling mechanism is due to stress and strain property of these materials. The experimentally obtained macroscopic characterization data is important in order to gain a guideline for the development of modeling tools for mechanics. The essence of the characterization for these materials is a detailed description of the mechanical, electromechanical, magneto-mechanical, and over all of the three fields coupled constitutive laws. A set up is constructed to apply simultaneously electrical, magnetic and mechanical field in order to quantify the interactions between fields and specimen. Further, in order to quantify the magnetic properties has been developed a special pressure cell, which allows magnetic measurement under load.
