Superparamagnets are tiny magnetic particles that can be found in materials like iron oxide. Unlike regular magnets, which have a fixed magnetic direction, superparamagnets can randomly flip their magnetic orientation when exposed to heat or an external magnetic field. This behavior occurs because the particles are small enough that thermal energy can overcome their magnetic interactions. These materials are often used in applications such as data storage and medical imaging. Their unique properties allow for high sensitivity and efficiency, making them valuable in technologies like MRI and magnetic nanoparticles for targeted drug delivery.
