Abstract
There is today a growing interest for ferroic materials. Some of them are ferroelectric, ferromagnetic or flexoelectric. Some materials are multiferroic, being both ferroelectric and ferromagnetic Multiferroic materials are rare. The present study showed that the ammonium sulphate, gotten from ammonium metavanadate and sulphuric acid is ferroelectric and ferromagnetic. There are electric dipoles at the surface and also inside the material. The electric signal was recorded and visualized. The Fourier transform carried out shown, in the angular frequency spectrum, the presence of four main lines. The drawing of the profiles of the two highest lines showed that they have doubly peaked profiles.
