Abstract:
Magnetic nanoparticles Researchers from worldwide believe that Superparamagnetism is a form of magnetism, which appears only in small ferromagnetic or ferrimagnetic nanoparticles but contrast to this concept Superparamagnetism has been discovered in diamagnetic nanoparticles. The researcher Ms.Theivasanthi (PACR Polytechnic College, Rajapalayam, India) who has discovered this breakthrough advancement comments: Invention of room temperature Superparamagnetism in diamagnetic nanoparticles is another milestone in nanoparticles / superparamagnetism research activities and it will lead to new concept in magnetic research. Recently, VSM analysis of the sample nanomaterial (diamagnetic) has been done at IIT Madras (India). The preliminary research result / figure confirm superparamagnetic behavior. Further research on this issue is undergoing.
