Lecture

Nano Magnetism: Recording and Magnetization

Description

This lecture explores nano-magnetism, focusing on the synthesis of magnetic particles by bacteria, magnetic random access memory, high-density magnetic recording trends, and the recording mechanism using ferromagnetic materials. It delves into the origin of magnetic moments, the storage media, and the magnetism of isolated atoms. The lecture also covers the Stern-Gerlach experiment, paramagnetic atoms, and the quenching of orbital and spin moments due to bond formation. Additionally, it discusses the Stoner model for spontaneous magnetization, spin behavior in transition metals, and examples of magnetization in multi-element clusters and rare earth materials.
