Abstract
The magnetic and electronic properties of Pd2S4 monolayer were done through doping nonmetals NM(N,P,As,O,Se,F,Cl,Br) and by using first principal calculations. The results show that nonmetals with an odd number of valence layers motivate magnetization of the structure, while non-metals with an even number in the valence layer do not induce magnetic property in the system. The highest amount of magnetization generated is due to the doping of seventh group atoms and especially the Br atom with a value of 0.81 µB. In the fifth group, from top to bottom (increasing the period), the value of spin-orbital p separation decreases, which corresponds to a decrease in the value of magnetization. While the value of spin-orbital separation P of the atoms of the seventh group increases with the increase of the period, so the value of magnetization of the atom The seventh group increases from the top to the bottom of the periodic table. In the seventh group, in contrast to the fifth group, the magnetization of the first neighboring sulfur atom is higher than that of the doping non-metal atoms. The findings obtained in this work can initiate experimental exploration and expand the application of non-metal doping in spintronic devices.
