Abstract: A survey of the development of magnetoelectric materials is given. The limitations of single phase materials is shown. The concept of magnetoelectric composites will be discussed. A measuring method based on modulating the dc-field and using a lock-in amplifier for determining the magnetoelectric coefficient is described. Results obtained for a composite of 50% BaTiO_3 and 50%CoFe_2O_4 are demonstrated.

Keywords: Magnetoelectric materials, measuring methods
