Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
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.
