27-445 Structure, Properties and Performance Relationships in Magnetic Materials

9 units, Carnegie Mellon University

This course introduces the student to intrinsic properties of magnetic materials including magnetic dipole moments, magnetization, exchange coupling, magnetic anisotropy and magnetostriction. This is followed by discussion of extrinsic properties including magnetic hysteresis, frequency dependent magnetic response and magnetic losses. This will serve as the basis for discussing phase relations and structureproperties relationships in various transition metal magnetic materials classes including iron, cobalt and nickel elemental magnets, ironsilicon, ironnickel, ironcobalt and iron platinum. This will be followed by a discussion of rare earth permanent magnets, magnetic oxides, amorphous and nanocomposite magnets. Polymers used in Electromagnetic Interference EMI Absorbers applications will also be covered.
