CATALOG DESCRIPTION: Introduction to the physical principles underlying the dielectric and magnetic properties of solids. Processing- microstructure- property relationships of dielectric materials, including piezoelectric, pyroelectric, and ferroelectric oxides, and of magnetic materials, including hard- and soft ferromagnets, ferrites and magneto- optic and - resistive materials, and includes descriptions of magnetic disc data storage principles and methods. The course also covers the properties of grain boundary devices (including varistors) as well as ion- conducting and mixed conducting materials for applications in various devices such as chemical sensors, fuel cells, and electric batteries. COURSE PREREQUISITES: Physics 7. A- 7. B- 7. C or Physics 7. A- 7. B and consent of instructor. MSE 1. 11 is recommended. PREREQUISITE KNOWLEDGE AND/OR SKILLS TEXTBOOK(S) AND/OR OTHER REQUIRED MATERIAL: Required text: A. Herbert, Electroceramcis, Chapman& Hall, second edition. Class notes provided on website, as necessary. COURSE OBJECTIVES: Introduce basic principles of dielectric and magnetic properties of solids. Discuss dielectrics in DC and AC fields. Familiarize students with magnetic disc data storage principles and technology. 1 Review of dielectric and magnetic materials Dielectric properties of materials are due to atomic-scale electric dipoles. Atoms and molecules have induced dipoles so that when an electric eld is applied they have a dipole. DESIRED COURSE OUTCOMES: Upon completion of the course, the successful student: Develops understanding of the fundamentals of polarizable solids, ferroelectricity, and magnetism. Is able to relate this to the functioning of device that exploit these properties. Understand how these properties may be used in device design. Is familiar with the principles and applications of electrochemical devices, in particular fuel cells and batteries. TOPICS COVERED: Background: review of physic principle of polarizable materials. Dielectric materials and polarization: effects of DC and AC fields; AC impedance. Dielectric applications: capacitors and CMOS and FET devices. Ferroelectric materials: basic properties and relationships, and applications. Modification of ferroelectric properties: defect chemistry and equilibria. Grain boundary devices. Magnetic materials: principles and applications. Electrochemical devices principles and applications to fuel cells and batteries. COURSE FORMAT: Three hours of lecture per week. CONTRIBUTION OF THE COURSE TO MEETING THE PROFESSIONAL COMPONENT: This course contributes primarily to the students’ knowledge of engineering topics. Design concepts are explored in some homeworks. RELATIONSHIP OF THE COURSE TO UNDERGRADUATE DEGREE PROGRAM OBJECTIVES: This course provides valuable information on the physical principles by which numerous practical devices function.
