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... |
