Abstract:
Magnetic two-dimensional materials have attracted considerable attention for their significant potential application in spintronics. Here, we systematically study the electronic structures and magnetic properties of a 3d transition metal doped InSe monolayer based on density functional theory (DFT). Our results show that InSe monolayer can be turned into a half-metal when the Ti, Cr, or Ni atom is doped. Further calculations indicate that the Cr-InSe monolayer possesses a robust ferromagnetic ground state due to the effective p-d exchange. The predicted Curie temperature of Cr-InSe is above the room temperature, showing a powerful potential in spintronics. Application in the spin valve is also explored using quantum transport simulations. Our results indicate that the magnetoresistance of a Cr-InSe spin valve attains 100% due to the half-metallic characteristics. These findings may pave the way for designing 2D nano-devices for future spin transport applications.

Properties of Transition Metals
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
