Spintronics in Low-Dimensional Materials

Spintronics, a branch of science, focuses on utilizing the electronic spin for information processing. Spintronics devices with low dimensionality, high spin polarization, and elevated Curie temperature (TC_C) are highly sought after for practical applications.  Among these, half-metal-based spintronics devices have garnered significant attention due to their nearly 100% spin polarization.  These materials exhibit a sharp contrast in electronic density near the Fermi level between spin-up and spin-down channels. This unique property allows half-metallic systems to generate fully spin-polarized currents, making them ideal for spin-filter systems. Such characteristics are particularly advantageous for developing spin-logic-based circuits. You can read our recent articles here and more in publications:
