Article Synopsis
- Scientists studied tiny magnetic particles (about 3 nanometers wide) to see how they behave when cooled using special methods.
- They found that the way these particles interact with each other affects how strong their magnetism is, especially in different types of samples.
- The research shows that by changing the design of these tiny particles, it's possible to control their magnetic properties, which could help in making better tech in the future.
The heat produced by magnetic nanoparticles, when they are submitted to a time-varying magnetic field, has been used in many auspicious biotechnological applications. In the search for better performance in terms of the specific power absorption (SPA) index, researchers have studied the influence of the chemical composition, size and dispersion, shape, and exchange stiffness in morphochemical structures. Monodisperse assemblies of magnetic nanoparticles have been produced using elaborate synthetic procedures, where the product is generally dispersed in organic solvents.
