Abstract:
The new era of technology imposes for better performances, better materials. The possibility of using electrons` spins in addition to their charge in information technology has created much enthusiasm for a new field of electronics popularly known as "spintronics." An intensely studied approach to obtaining spin-polarized carriers for data-storage devices is the use of diluted magnetic semiconductors created by doping ions like Mn, Fe, or Co having a net spin into a semiconducting host such as GaAs, ZnO, or GaN. The interaction among these spins leads to ferromagnetic order at low temperatures, which is necessary to create spin-polarized carriers.
In our work we have computed several substances of witch we now their properties. We have added in the basic matrix some magnetic particles from groups 3d or 4f in order to create some new substances that present magnetic properties. From simulations we have concluded about their properties.
