DESCRIPTION: The subject of ferromagnetsm – its materials, properties, function, applicability, etc., has been traditionally neglected at the university level (much to the distress of major industries). Only recently, with the increased demand and economic opportunity, for major innovations in this field, has advanced level courses been offered here at MIT. We shall attempt at this series of meetings to provide a basic introductory level to this subject – not readily available otherwise.
Topics to be covered include:
1. the energies involved in creating and analyzing the phenomena of collective magnetic behavior in materials,
2. the effect of geometry on the energies and thus on the magnetic properties. Included are specialized properties of miniaturization and lower dimensionality.
3. Hard permanent magnets – obtaining large coercive forces as functions of atomic structure, material workability and associated lattice defects, grain boundaries, and such; as used in motors, train levitation, etc.
4. Soft magnetic materials as used in transformers for current and energy distribution.
5. magnets as used in computers, smart phones, and electronic design where requirement of size, stability, response time, and temperature control are key.
