Abstract: The aim of the present work has been to synthesize and to investigate crystal and spin structure in some geometrical and spin spiral multiferroics. Multiferroic materials exhibit two or more ferroic properties such as, ferroelectricity, ferromagnetism and ferroelasticity. These materials are considered as prime candidates for future computer data storage and spintronics. There are several classes of magnetoelectric multiferroics classified based on the origin of multiferroicity. The two types of multiferroic compounds investigated in the present dissertation are, geometrically frustrated systems including; hexagonal DyMnO3 (hDMO) and orthorhombic HoCrO3 (HCO) and spin spiral systems including wolframite type Mn0.9Co0.1WO4 (MCoW) and Mn0.9Cu0.1WO4 (MCuW). The samples were characterized by macroscopic techniques; specific heat and magnetization as well as microscopic techniques; x-ray diffraction and neutron scattering...
