What are Some Examples of Nanoscale Magnetic Materials?
There are several materials known for their fascinating magnetic properties at the nanoscale:
1. Magnetic Nanoparticles: These are particles of magnetic materials like iron oxide, cobalt, and nickel, ranging from 1 to 100 nm in size. They are used in hyperthermia treatment for cancer and as contrast agents in MRI. 2. Magnetic Thin Films: Thin films of magnetic materials exhibit unique properties like giant magnetoresistance (GMR), which have revolutionized the data storage industry. 3. Magnetic Nanowires: These one-dimensional structures have potential applications in spintronics and magnetic sensing devices due to their unique anisotropic magnetic properties.
