Despite its promise, spintronics faces several challenges:
Spin injection efficiency: Efficiently injecting spin-polarized electrons into non-magnetic materials remains a significant hurdle. Spin coherence: Maintaining the spin state over long distances and times is difficult due to interactions with the environment. Material compatibility: Developing materials that can effectively integrate into existing semiconductor technology is essential for practical applications. Scalability: Manufacturing spintronic devices at a nanoscale while maintaining performance and reliability is a complex challenge.
