Lecture
This lecture covers the different types of magnetism, including ferromagnetic, paramagnetic, and antiferromagnetic behaviors, as well as superparamagnetism in nanoparticles. It explains the variations in magnetic susceptibility with temperature, the concept of magnetic domains in nanodots and large particles, and the applications of nanomagnetism in magnetic data storage. The instructor also discusses anisotropy energy, magnetic domains in thin films, and nanoscale transistors for GHz to THz electronics.
