Despite the promising applications, there are challenges in the field of nanoscale magnetism:
1. Stability: Nanoscale magnetic materials can be chemically unstable and may oxidize or degrade over time. 2. Scalability: Synthesizing these materials on a large scale while maintaining uniform properties can be challenging. 3. Safety and Toxicity: The long-term effects of exposure to magnetic nanoparticles are not well understood, necessitating thorough toxicological studies.
