Based on the yttrium garnet ferrite, a composite rareearth garnet ferrite with low magnetic moments, YGdCaVInIG, was designed and prepared to meet the need of super power device which works in low field at a few hundreds of megahertz bands.

Quality of magnetic moment of bilayer honeycomb Ising model;

The characters of bilayer superlattice Ising model magnetic moment;

The complexes have been characterized by elemental analysis,IR,electronic spectra,molar conductance and magnetic moments at room temperature.

The structural stabilities and magnetic moments of the pseudomorphic Fe ovedayers on Mo (110) substrates are studied by using first-principle plane wave pseudopotential method based on the density functional theory.

We calculate their masses and magnetic moments and discuss their possible strong decays using the chiral Lagrangian formalism.

The influences of the coupling of ground multistate of Nd 3+ ions in Nd:YIG on the magnetization and magneto-optical effects are calculated by using quantum theory.

The influence of the spin-orbit coupling of the ground configuration on the magnetization, the magneto-optical effects and the magneto-optical coefficient are calculated by using quantum theory.

The structure and magnetic properties of these compounds were investigated by X-ray diffraction and magnetization mea- surements.
