Note: In nanospintronics technology, spin or the intrinsic angular momentum of the electron is considered to be the way to use this factor for two important discoveries based on this technology. First, resistance tunneling phenomenon was predicted. Based on this phenomenon, the degree of electron tunneling from an insulating layer can be called magnetization by placing two ferromagnetic layers on both sides of it and manipulating the relative direction of magnetization of these two. But this phenomenon alone controlled the ability of the layer.
In the structure of "nano spin electrons", the electronic quantity that is more easily accessible is the ionization potential. The ionization potential is greater in the size of small grains (smaller particles), that is, with the increase in the size of "nano spin electrons", their ionization potential decreases. The ratio of surface area to volume and changes in geometry and electronic structure have a strong effect on the chemical interactions of matter, and for example, the activity of small particles changes with changes in the number of atoms (and thus the size of the particles).
How to produce and reproduce "nano spin electrons" and electronic properties:
In general, chemical reactions to produce materials can take place in any of the solid, liquid, and gas states. The common method for producing solid materials is that by crushing "nano-spin electrons" , their contact surface is increased, and in order to increase the penetration of atoms and ions, this mixture is increased at high temperatures. Although "nano-spin electrons"are not attracted to each other due to but due to the high energy of the surfaces, electromagnetic nanoparticles tend to accumulate . The electrostatic stability of nanomolecules is not suitable for nanoparticles; Although the repulsion of charges on the surface of "nano spin electrons" can prevent their accumulation, But in the presence of a catalyst or other electrolytes in the internal environment of electromagnetic nanoparticles, these charges are neutralized.
Conclusion :
In nanospintronics technology, spin or the intrinsic angular momentum of the electron is considered to be the way to use this factor for two important discoveries based on this technology. First, resistance tunneling phenomenon was predicted. Based on this phenomenon, the degree of electron tunneling from an insulating layer can be called magnetization by placing two ferromagnetic layers on both sides of it and manipulating the relative direction of magnetization of these two. But this phenomenon alone controlled the ability of the layer.
